    Description: Roads fragment wildlife habitat, and the vehicles that travel them are often a source of wildlife mortality. Often, wildlife populations can absorb this unnatural mortality without suffering declines, but for endangered large mammals like the Florida panther, if their remaining habitat is fragmented or their mortality is increased in other ways (e.g., roadkill), their existence may be imperiled. A landscape approach is critical to identifying key road segments that are important for maintaining unimpeded panther movement. Least-cost pathway (LCP) modeling considers elements within the landscape that facilitate movement and minimize impediments when an animal travels from one area to another. Our analyses identified the most likely LCPs for panthers to use in moving between six major use areas in southwest Florida, and we identified 16 key road segments where these LCPs intersected improved roadways. These intersections correlated well with documented panther roadkill locations and overlapped fixed-kernel panther home ranges. One of our LCPs coursed through an area dominated by citrus groves; this area is strategically located between large blocks of panther habitat, which explains the cluster of panther roadkills at this location. Our analyses supported the habitat stewardship areas of the 2002 Collier County Rural Lands Stewardship Plan; however, we recommend additional protection for the pathway north of County Road 858 and west of State Road 29. We believe that by using a landscape approach, panthers and their habitat can be protected as current road networks are improved, new roads are constructed, and existing panther habitat is altered or disturbed. We did not attempt to map all possible panther–road conflict areas; however, this technique could be applied to other areas, such as possible panther reintroduction areas, as needs arise.

    Description: Manatees wintering in Tampa Bay, Florida, were captured and fitted with satellite- and radio-telemetry equipment during a research project conducted from 1991 to 1996. Forty-four manatees were tagged after their capture in Tampa Bay; an additional 15 animals were tagged at other west coast locations. Locations of individual animals were estimated via satellite up to eight times per day, and observations of manatee locations were made in the field one or more times per week. These data were entered into a relational database and converted to a format accessible as points within a geographic information system (GIS). Seasonal densities of satellite locations were mapped for 33 manatees tagged in Tampa Bay. Within the bay, manatees aggregated at or near warm-water locations during winter. In other seasons, manatee density was highest in areas that had abundant sea grass and were close to fresh-water sources. Sequential data points for individual manatees were transformed into probable travel routes by using a GIS-based cost-path analysis. A map was created for each tagged manatee depicting estimated travel paths, and detailed descriptive information summarized major movements, tagging history, and physical characteristics. The travel patterns of male manatees were characterized by almost continual movement, often along predictable routes or circuits. Most males larger than 265 cm ranged 100 km or more away from Tampa Bay during non-winter months whereas smaller males remained in or near the bay. As males matured, their travel ranges appeared to expand. Female manatees used two general movement patterns. Small females and females with calves would use specific areas within a day’s travel of the warm-water sources for extended periods before moving to similar nearby areas for protracted stays. Females without calves and females longer than 330 cm with calves added long migrations between areas chosen for foraging.The ranges of some females extended south to Charlotte Harbor,the Caloosahatchee River,and the Everglades. Two tagged females traveled from Florida’s west coast to the east coast: one traveled south around the peninsula, and the other apparently moved east through Lake Okeechobee and the lock system.

    Description: This is the second edition of the Seagrass Integrated Mapping and Monitoring (SIMM) report, providing mapping and monitoring information for seagrasses throughout Florida’s coastal waters. Each regional chapter has been updated, and we have added information on management programs and water quality and clarity. For most regions, seagrass maps nowshow data gathered between 2010 and 2014. Exceptions include the Big Bend, Cedar Keys, Waccasassa Bay, the Charlotte Harbor region, Estero Bay, the Ten Thousand Islands, and Biscayne Bay; however, imagery was acquired in 2014 or 2015 with photo-interpretation underway for these remaining regions except Cedar Keys, Waccasassa Bay, and Biscayne Bay.The primary indicators derived from mapping projects are seagrass areal coverage and habitat texture (i.e., continuous or patchy). Secondary indicators of seagrass condition and health determined by mapping projects are estimates of gains and losses in cover and changes in texture determined from analyses of two most recent sets of imagery having the same spatial extent. Where successive imagery data sets are available, we have updated changes in seagrass acreage.

    Description: The Spotted Seatrout Cynoscion nebulosus (Sciaenidae) is an estuarine fish of economic importance, commercially and recreationally, in Florida. Harvesting of this fish has been steadily decreasing since the 1950s. In the late 1980s, the Florida Fish and Wildlife Conservation Commission (FWC) implemented a major effort to stop the decline in landings and classified the species as restricted, regulating the importation, transportation, and possession of these fish. Over the period 1981-2012, combined recreational and commercial landings of Spotted Seatrout have been flat, primarily because of regulation of the fishery. In the absence of a well-resolved population genetic structure for the Spotted Seatrout, the FWC has relied on coastal watershed features and reproductive differences among estuaries to demarcate regions for management purposes. ... In the present study we identify three genetic stocks of Spotted Seatrout in Florida waters, each with a unique range: 1) from the western border of Florida to Apalachicola Bay, 2) east of Apalachicola Bay through Biscayne Bay, and 3) from Sebastian Inlet to the northeast border of the state. The genetic patterns observed indicate that little if any contemporaneous reproductive exchange takes place between these stocks and that recruitment usually occurs in the natal estuary. The geographic boundaries that frame the FWC’s periodic stock assessments and other demographic evaluations of Spotted Seatrout are not a perfect match with those of the genetically identified stocks. We recommend that, in its assessments of Florida stock of the Spotted Seatrout, the FWC use the genetic stock boundaries that we describe here.

    Description: This Florida Fish and Wildlife Conservation Commission–Fish and Wildlife Research Institute (FWC-FWRI) Technical Report describes and summarizes the FWC-FWRI aerial-survey projects conducted from 1984 to 2004 to document manatee distribution in Florida and it provides details of the methods used in the studies. Surveys reported here were conducted by FWC or in conjunction with other agencies. This report is intended for use by local, state, and federal agencies and others involved in assessing the impacts of human activities on manatees and their habitat. It provides basic summaries of these surveys, their methods, the resulting data, and includes maps showing where manatees were sighted. Aerial survey data (manatee sightings and flight routes) from this technical report are available in a Geographic Information System (GIS) computer mapping format (shapefiles) on the FWC–FMRI Atlas of Marine Resources CD–ROM or on the FWC website. The analyses reported do not address in detail the environmental and habitat factors that may influence aerial surveys. The data and analyses described in this report provide a starting point for researchers who want to further investigate the seasonal distribution and habitat use of manatees in Florida. Other available data sets pertaining to manatee management and protection are also described. The information presented in this document is current to 2004 and does not include projects or surveys conducted after 2004.

    Description: Three of the 20 species in the genus Trachinotus, in the jack family, Carangidae, are found in Florida waters. These are Florida Pompano (T. carolinus), Permit (T. falcatus), and Palometa (T. goodei). Florida Pompano is a coastal pelagic species found in estuarine and marine waters; it spawns in multiple batches in offshore waters. Permit is the largest and longest lived of the three species and also spawns offshore in multiple batches, near reefs. As adults, Permit can be found nearshore and offshore and are often associated with reefs, but as juveniles they are common estuarine inhabitants. Palometa is a marine species, similar in size to Florida Pompano, and has the widest latitudinal distribution of the three species. Palometa spawn in offshore waters throughout the year with two peaks of activity. All three species support commercial or recreational fisheries on both the Gulf of Mexico coast and Atlantic coast of Florida. Very little has been done to evaluate movement patterns of Trachinotus species. Based on a few tagging studies, it appears that Pompano do not travel far from coastal waters. The only preliminary investigation of genetic stock structure for the Florida Pompano population from Tampa Bay, FL, and Puerto Rico was based on microsatellite markers developed for the Pompano. The report’s key conclusion was that Pompano from Puerto Rico and from Florida belong to two highly distinct genetic stocks. This study was conducted to re-examine, using different microsatellite markers, the genetic status of Pompano stocks in Florida and Puerto Rico. The objectives of this study, therefore, were the following: 1) to develop microsatellite markers for Permit; 2) to cross-amplify the markers in Pompano and Palometa; and 3) to use these markers to confirm the status of Puerto Rico Pompano as a novel genetic stock using the methods of Bayesian population assignment, phylogenetic clustering, and factorial correspondence analysis. ... Three methods were used to investigate the relationship among the taxa using the microsatellite genotype data obtained from the samples. The results from the three analytical methods, based on Bayesian population assignment tests, phylogenetic clustering, and factorial correspondence analysis of genetic relationships among the four Trachinotus samples, showed that Florida and Puerto Rico Pompano samples belong to two highly distinct gene pools. But other multiple molecular tools, particularly nuclear-DNA sequences from many introns, and nonmolecular tools, such as morphological and meristic data, should be used together to determine species-level categorical designation for the Puerto Rico Pompano.

    Description: Mangrove swamps and salt marshes provide valuable ecological services to coastal ecosystems in Florida. Coastal wetlands are an important nursery for many ecologically and commercially important fish and invertebrates. The vegetation stabilizes shorelines, protecting the coast from wave energy, storm surge, and erosion. Coastal wetlands are also able to filter surface water runoff, removing excess nutrients and many pollutants. Peat deposits sequester large amounts of carbon, making coastal wetlands a key sink in global carbon cycles.Mangroves and salt marshes, however, are vulnerable to both direct and indirect threats from human development. Current threats include continued habitat loss, hydrologic alteration of surface and groundwater, sea-level rise, and invasive vegetation. ... Coastal wetland monitoring programs are often short-lived and vary widely in methodology. Monitoring most commonly occurs on protected public lands or at wetland mitigation or restoration sites. These monitoring projects are rarely long-term due to a lack of funding; restoration sites are generally monitored for only a few years. Although long-term funding is difficult to secure, monitoring over long time scales is increasingly important due to regional uncertainties as to how coastal wetland vegetation and substrate accretion will respond to sea-level rise, altered freshwater hydrology, and other disturbances. While periodic land cover mapping programs can capture large-scale changes in habitat extent, smaller-scale species shifts among mangrove and salt marsh vegetation are best captured by on-the-ground monitoring.The chapters in this report summarize recent mapping and monitoring programs in each region of Florida. Content of each chapter includes a general introduction to the region, location-specific threats to salt marshes and mangroves, a summary of selected mapping and monitoring programs, and recommendations for protection, management, and monitoring. Land cover maps in this report generally use data from the most recent water management district land use/land cover (LULC) maps.

    Description: Oysters provide a variety of critical ecosystem services to coastal communities in Florida. They improve water quality and clarity as they filter feed, lessen shoreline erosion, and provide a habitat or food source for a wide variety of birds, fish, and invertebrates. Oysters are commercially valuable as a harvested food source, and historically their shell has been mined extensively for construction material. The eastern oyster (Crassostrea virginica) is the only reef-building oyster in Florida and forms both subtidal and intertidal reefs. Numerous other species of non-reef-building oysters are less frequent. This report focuses primarily on the eastern oyster, because it is the most abundant oyster in Florida and because it is important as both a keystone species and an ecosystem engineer.

    Description: Knowing how many manatees live in Florida is critical for conservation and management of this threatened species. Martin and others flew aerial surveys in 2011–2012 and estimated abundance in those years using advanced techniques that incorporated multiple data sources. We flew additional aerial surveys in 2015–2016 to count manatees and again applied advanced statistical techniques to estimate their abundance. We also made several methodological advances over the earlier work, including accounting for how sea state (water surface conditions) and synchronous surfacing behavior affect the availability of manatees to be detected and incorporating all parts of Florida in the area of inference. We estimate that the number of manatees in Florida in 2015–2016 was 8,810 (95% Bayesian credible interval 7,520–10,280), of which 4,810 (3,820–6,010) were on the west coast of Florida and 4,000 (3,240–4,910) were on the east coast. These estimates and associated uncertainty, in addition to being of immediate value to wildlife managers, are essential new data for incorporation into integrated population models and population viability analyses.

    Description: The shoaling and bank erosion at Ponce de Leon channel, Punta Gorda, Florida, havecaused concern of harming the mangrove community along the channel. Three factorswere identified that could contribute to the bank erosion of Ponce channel. Theyare tidal induced current, wind waves penetrating from the Charlotte Harbor, andwakes caused by boat traffic. According to the field experiments and numericalmodeling studies, it was determined that the combined wind wave and tidal currentforce is the major cause to the bank erosion. Wind wave appears to play a moreimportant role because of its dynamic nature. For the present cross-sectionalchannel condition the tidal current alone is only a moderate erosional force.It was also found that reopening the barge canal would cut the tidal currentstrength in the Ponce channel by a half. This current reduction would reduce butnot eliminate bank erosion in the lower reach as the wind-wave induced force willremain to be an important erosional factor.A number of remedial alternatives were given in the report. The most direct methodis to provide bank protection. The extent of the protection depends upon theextent of wind wave penetration which could be as deep as 150 m into the channelunder the present channel entrance condition.

    Description: Abstract of Thesis Presented to the Graduate Schoolof the University of Florida in Partial Fulfillment of theRequirements for the Degree of Master of EngineeringVIDEO MONITORING TECHNIQUES IN THECOASTAL ENVIRONMENTByThe field of coastal engineering has primarily utilized traditional measurementtechniques such as boat surveys and beach profiles. Aerial photography has played amajor role in the mapping of coastlines and ocean currents. More recent technology hasprovided the ability to make field measurements with precision electronicinstrumentation, but the problem of making large-scale measurements within economicbounds remains. The video revolution and, in particular, desktop video has greatlyenhanced the ability of scientists and engineers to visualize events over greater periods oftime and larger scales than ever before.The uses of video, benefits, shortcomings, and future expectations are presentedas applicable to the field of coastal engineering. This feasibility study incorporates someapplications which have previously been explored, as well as others which result fromtwo unique video data sets that were collected between 1991 and the present.

    Description: A method of predicting equilibrium scour depths around multiple pile structuresbased on pre-scoured bottom shear stress was developed in this study. It washypothesized that a relationship exists between the pre-scoured bottom shear stress andthe equilibrium scour depth. A series of hydrodynamic tests were conducted in whichnear-bottom flow measurements were made in the vicinity of a variety of multiple pilestructures. The distribution of bottom shear stress was estimated from these flowmeasurements. Scour tests were then made in the same flume using the same structures.A simple relationship between the equilibrium scour depth and the pre-scoured bottomshear stress was formulated and the data from the two sets of experiments were used tocalibrate and test the formulation. The formulation gives reasonable predictions for therange of conditions tested. The approach appears promising as an alternative way of estimating equilibrium local scour depths for complex multiple pile structures. Inaddition, a number of interesting and useful findings were made regarding the rate atwhich a local scour hole forms near complex structures. (Document contains 146 pages.)

    Description: This is the first of a pair of reports documenting the effects of storms on barrier island systems.The present report (Volume 1) investigates storm effects on natural island conditions whereasVolume 2 addresses the effects of seawalls. With the aim of simulating the effects of overwashon barrier islands and characterizing their response, a series of nine experiments was conductedat the Coastal Engineering Laboratory of the University of Florida. The barrier island wassimulated by a 400 feet wide (prototype units) horizontal crest and an initially planar (1:19)beach. The effects of various storm surge levels and accompanying overtopping were investigated.Experiments were conducted with both regular and irregular storm waves. Regularwaves without overtopping caused the formation of a substantial berm in the swash zone and aprominent longshore bar offshore. Increasing degrees of overtopping resulted in substantial lossof sand from the barrier island system. The longshore bar was considerably more subtle for thehighest water level tested (11.5 ft. above mean sea level). Simulation of a storm-surge hydrographwith rising and falling water levels indicated that the presence of the bar tends to occuronly during a relatively steady or slowly changing water level. The experiments with irregularwaves were conducted with reasonably similar wave heights and carrier periods as those withregular waves. The major difference was in the characteristics of the longshore bar response. Incomparison with cases with regular waves, the bar was less distinct without overtopping, subtlewith minimal overtopping and absent in cases with substantial overtopping. These experimentsseem to indicate that offshore bars are simply break-point bars which require a fairly steadybreak-point and undertow (return of mass transport) for optimal formation.

    Description: This report presents results of the experiments of the existing inlet and eightstructural alternatives to the Sebastian Inlet from a movable bed model. It is intendedto find solutions for improvement of boating safety and protection of beaches adjacentto the inlet. Based upon the experimental results from here and the fixed bed modelstudy, which is summarized in Part I report, an optimum structural modification planwas then recommended providing a general frame of improvement scheme.The research in this report was authorized by the Sebastian Inlet District Commissionof September 15, 1989. The University of Florida was notified to proceedon November 14, 1989. The study and report were prepared by the Department ofCoastal and Oceanographic Engineering, University of Florida. Coastal TechnologyCorporation was the technical monitor representing the Sebastian Inlet District. (Document has 109 pages.)

    Description: This thesis examines the historical shoreline response to inlet modifications and sealevel rise. Inlet modifications are considered to be the geographic stabilization and training(through the use of structures) of natural inlets and the creation and further modification ofartificial inlets. Shoreline response to natural and artificial processes must be understood inorder to predict the performance of the coastline. The tendency for creating and modifyinginlets increases as industry and population growth demands. Sea level rise is a natural processwhich cannot be controlled at this time. Current theoretical approaches to predictingshoreline response indicate that sea level rise and inlet modifications can cause substantialshoreline impact. Florida, with roughly a century of shoreline position and relative sea leveldata, provides a basis for examining past trends and comparing them with theory.The shoreline of Florida was found to be accreting with the greatest accretion alongthe east coast. Shoreline responses within the boundaries of the erosional influence of inletsdue to their creation and/or modification were examined for 19 inlets around the coast ofFlorida. The differences in the shoreline response before and after the initial modification ofeach inlet show the erosional strain that inlets apply on the nearby shoreline. The effect onshoreline response due to the human intervention (unnatural processes) of modifying inletswas isolated and examined. The shoreline response due to this "human intervention" was erosional, thereby showing the negative impact that modified inlets have on shorelines. Thisinduced erosion is responsible for the loss of roughly 21.6 million cubic yards of sand from theshoreline that is within the erosional influence of Florida's east coast inlets. Combining theshoreline changes due only to natural processes with sea level rise data allows for comparisonwith the commonly accepted Bruun Rule for shoreline response as a result of a changingsea level. This comparison and the effects of including a lag time between a rise in sea leveland a change in shoreline along the east coast of Florida during the last century show noagreement with the Bruun Rule and no correlation with a specific lag time.

    Description: This is the second of a pair of reports documenting the effects of storms on beach systemsincluding the presence of seawalls. With the aim of simulating the effects of overwash onbarrier islands with seawalls and characterizing their response, a series of eight experimentswas conducted at the Coastal Engineering Laboratory of the University of Florida. The barrierisland was simulated by a 400 feet wide horizontal crest and an initially uniform mildly-sloped(1:19) beach. The effects of positioning the seawall at two different locations as well as the effectsof various storm surge levels and accompanying overtopping were investigated. Experimentswere conducted with both regular and irregular storm waves. With the seawall located at theslope break between the crest and the sloping beach of the barrier island, and the crest of theseawall just submerged in sand, the effects on the sediment transport process were found to beminimal. For the same position of the seawall but with the crest of the seawall raised above thesurrounding ground level, overtopping caused washover of sand indicating substantial transportin suspension. Increased levels of overtopping tended to accentuate bed profile changes butsupress bar formation (as did irregular waves). Positioning the seawall at the Mean Sea Levelshoreline caused significant scour both immediately landward as well as immediately seawardof the seawall. A prominent scour trough developed further seaward. The longshore bar washighly three-dimensional. It appears that seawalls need to be located adequately landward of theshoreline to discharge their function effectively without adverse effect to the beach. In addition,concerns for safety warrant the presence of an adequate buffer-zone between the seawall andthe upland property. (61 pp.)

    Description: The genus Synalpheus Bate, 1888, is one of the most diverse and widely distributed generaof caridean shrimps in the world. Often known as snapping shrimps because of the popping soundmade by the major first pereopod when the chela is closed rapidly, members of this genus areimportant components of coral reef and live bottom communities in all tropical and subtropical seas.The Gambarelloides group (a well-defined, homogeneous group within the genus but lackingformal subgeneric status) contains over half the described species of Synalpheus in the Gulf ofMexico and Caribbean. Its many species are distinguished from each other by subtle, and oftenvariable, characters. Accurate inventories of the Gulf fauna have been handicapped by difficulty inseparating these shrimps at the specific level. Distributional data, diagnoses, and references toeach of the 19 species of the group from the Western Atlantic Region are presented in this report.The 11 species known from the Gulf of Mexico are illustrated. Details of specific ecological associations,morphological variation, and life history strategies are also summarized. (Document has 125 pages.)

    Description: Current plant canopy wind flow models require three aerodynamic parametersto predict the effects of wind on sand transport--the plant drag coefficient, Cd, the leafarea density profile, LAD, and the turbulent eddy transfer coefficient, 6,. The LADand Cd characterize the plant canopy and its effects on air flow and, prior to thisstudy, data on these parameters for dune vegetation did not exist. The purpose of thisstudy was to design and test a methodology for measuring the wind drag coefficient ofcoastal dune plants. The objectives were 1) to measure and record the parametersneeded to calculate Cd, namely, the force, relative velocity and air temperature; 2) tomeasure the leaf area density of sea-oats; 3) to validate the method by measuring thequantities needed to compute the drag coefficient for a right circular data exists; and 4) to explore the Reynolds number dependence of the canopy dragcoefficient.

    Description: Gulf sturgeon are anadromous. They spend thecooler months (October or November through Marchor April) in estuarine or marine habitats, where theyfeed on benthic organisms such as isopods, amphipods,lancets, molluscs, crabs, grass shrimp, and marineworms (Mason and Clugston, 1993). In the spring, gulfsturgeon return to their natal river, where the sexuallymature sturgeon spawn, and the population spendsthe next 6–8 months there (Odenkirk, 1989; Foster,1993; Clugston et al., 1995; Fox et al., 2000). The conservation plan detailed in this documentwill be used to aid recovery of gulf sturgeon populationsthroughout the state of Florida and could be amodel for other gulf states to use. (106pp.)

    Description: Making the public aware of light-pollution problemson sea turtle nesting beaches is a fundamentalstep towards darkening beaches for sea turtles. Manyof those responsible for errant lighting are unawareof its detrimental effects and are generally willing tocorrect the problem voluntarily once they become aware. Nonetheless, legislation requiring light managementis often needed, and on many nestingbeaches, it may be the only means to completelyresolve light-pollution problems. An outline for initiating,promoting, and implementing beach-lightinglegislation is presented in this manual along with amodel ordinance that can be used to help producelegislative drafts. (84pp.)

    Description: Management programs that address scarringof seagrasses should be based on an approach thatinvolves (1) education, (2) channel marking,(3) increased enforcement, and (4) limited-motoringzones. Aerial monitoring and photography ofthe managed area are essential in evaluating theeffectiveness of a program. Management programsthat use this multifaceted approach have beeninstituted by a few local governments and at severalstate parks. Initial results of the programsindicate that in some areas seagrass scarring hasbeen reduced but that in other areas emphasis mayneed to be increased on one or more of the componentsof the four-point approach. A statewidemanagement plan is needed to address the mostegregious scarring over large areas that may bedifficult to regulate at the local-government level.

    Description: This report documents the progress made toward theobjectives established in the Strategic Plan revised in1997 for the agencies cooperating in the program. These objectives are expressed as five questions that organized the research on the Florida Bay ecosystem: Ecosystem History What was the Florida Bay ecosystem like 50, 100, and 150 years ago? Question 1—Physical Processes How and at what rates do storms, changing freshwater flows, sea level rise, and local evaporation and precipitation influence circulation and salinity patterns within Florida Bay andexchange between the bay and adjacent waters? Question 2—Nutrient Dynamics What is the relative importance of the influx of external nutrients and of internal nutrient cycling in determining the nutrient budget for Florida Bay? What mechanisms control the sources and sinks of the bay’s nutrients? Question 3—Plankton Blooms What regulates the onset, persistence, and fate of planktonic algal bloomsin Florida Bay? Question 4—Seagrass Ecology What are the causes and mechanisms for the observed changes in the seagrass community of Florida Bay? What is the effect of changing salinity, light, and nutrient regimes on thesecommunities? Question 5—Higher Trophic Levels What is the relationship between environmental and habitat changeand the recruitment, growth, and survivorship of animals in Florida Bay?Each question examines different characteristics of the Florida Bay ecosystem and the relation of these to the geomorphological setting of the bay and to processes linking the bay with adjacent systems and driving change.This report also examines the additional question of what changes have occurred in Florida Bay over the past 150 years.

    Description: With the rapid growth and development of barrier islands, understanding the long-termstability of these islands is an integral part of future coastal planning. The overwash process isthe largest influence on the long-term stability of these islands and thus a correspondingunderstanding is of major importance. A laboratory experiment was undertaken to physicallymodel the wave and current forcing as they pertain to the overwash process. The physical modelwas subjected to various storm conditions common to the occurrence of the overwash.Combinations of wave height, wave period, and overwash depth were tested in an attempt toisolate the significant parameters. Water surface gradients were also applied to observe theirinfluence on the overwash process. Wave height, current, and bed profile measurements weretaken at different locations throughout the tank. In addition, wave height transformationmodeling and mean current prediction were performed and compared to the laboratory results inan attempt to model the overwash process through computer simulations.The experimental results demonstrate that the water surface gradient is the mechanismfor transporting large quantities of sand on to and over barrier islands. In addition, two otherconclusions were drawn about the overwash process: 1) the overwash depth plays an importantrole in determining the overwash velocity and hence the amount of sand deposited on the barrierisland. 2) There seems to exist a correlation between the strength of the return flow and barformation.It was also determined that modeling the wave height transformation during the overwashprocess is possible if the model is expressly written for the overwash process and not for nonoverwashingcases. The method utilized to predict the mean currents during overwash was notable to predict their strength but was able to substantiate the correlation between return flow andbar formation. As a result of overwash, the increased shoreward mass transport and reducedreturn flow in the water column are able to initiate and sustain a shoreward sediment transport.Finally, it was concluded that in all likelihood only "significant" overwash events affect the longtermstability of the barrier islands.

    Description: This report is to document the programs my colleague and I developed for computingtime-dependent nearshore hydrographic changes including beach profile responses.The time scale of the model is suitable for storm events to seasonalchanges, currently up to one year period. The model is very stable and is capableof handling complicated topographies including inlets and irregularly-shapedstructures such as curved jetties and breakwaters.The purpose of three-dimensional models is to predict the change of bottomtopography from the spatial distribution of the sediment transport rates, which areevaluated from the nearshore wave and current fields computed point by point insmall areas defined by a horizontal grid placed over the region of interest. Modelsof 3-D beach topography change require much fewer idealizations than do the linemodels. (Document has 43 pages.)

    Description: The objectives of this study were 1) to determine the maximum structure-inducedlocal sediment scour depths for the proposed bridge piers for the Merrill BarberBridge over Indian River on.State Road 60 in Indian River County, Florida and 2) todetermine the feasibility of predicting equilibrium local scour depths near complexmultiple pile bridge piers from bottom shear stresses on the prescoured bed. Aseries of hydrodynamic tests were conducted in a laboratory flume (100 ft long x 8 ftwide x 2 ft deep) where flow velocities near model piers were measured with a twocomponent constant temperature anemometer at a height of 3 mm above the bed. Bottomshear stresses were then estimated from the flow measurements. The piers (which are1/15 scale models of proposed Merrill Barber Bridge piers) consisted of thirtysixsquare piles (3 columns of 12) and a pile cap that was positioned at differentelevations above the bottom. Two different pile cap shapes were also considered. Asimple relationship between the prescoured bottom shear stress and the equilibriumlocal scour depth was postulated.Sediment scour tests were then conducted in the same flume with the samemodels. The average duration of these tests was 28 hours. Scour depths weremeasured periodically throughout these tests using an acoustic transponder. Thescour measurements were used 1) to establish the maximum scour depths for the MerrillBarber Bridge piers and 2) to calibrate and test the scour-shear stress relationship.Even though the range of conditions tested was somewhat limited, the approach appearspromising and should be pursued further. A number of interesting findings were maderegarding the rate at which scour occurs in these complex structures. (Document contains 134 pages.)

    Description: Part I. Relationships between the rate of bed fluidization and the rate of wave energy dissipation, by Jingzhi Feng and Ashish J. Mehta and Part II. In-situ rheometry for determining the dynamic response of bed, by David J.A. Williams and P. Rhodri Williams.A series of preliminary laboratory flume experiments were carried out to examine the time-dependentbehavior of a cohesive soil bed subjected to progressive, monochromatic waves. The bed was an aqueous,50/50 (by weight) mixture of a kaolinite and an attapulgite placed in a plexiglass trench. The nominal bedthickness was 16 cm with density ranging from 1170 to 1380 kg/m 3, and water above was 16 to 20 cmdeep. Waves of design height ranging from 2 to 8 cm and a nominal frequency of 1 Hz were run fordurations up to 2970 min. Part I of this report describes experiments meant to examine the rate at whichthe bed became fluidized, and its relation to the rate of wave energy dissipation. Part II gives results onin-situ rheometry used to track the associated changes in bed rigidity.Temporal and spatial changes of the effective stress were measured during the course of wave action,and from these changes the bed fluidization rate was calculated. A wave-mud interaction model developedin a companion study was employed to calculate the rate of wave energy dissipation. The dependence ofthe rate of fluidization on the rate of energy dissipation was then explored.Fluidization, which seemingly proceeded down from the bed surface, occurred as a result of the lossof structural integrity of the soil matrix through a buildup of the excess pore pressure and the associated loss of effective stress. The rate of fluidization was typically greater at the beginning of wave action andapparently approached zero with time. This trend coincided with the approach of the rate of energydissipation to a constant value. In general it was also observed that, for a given wave frequency, the largerthe wave height the faster the rate of fluidization and thicker the fluid mud layer formed. On the otherhand, increasing the time of bed consolidation prior to wave action decreased the fluidization rate due togreater bed rigidity. Upon cessation of wave action structural recovery followed.Dynamic rigidity was measured by specially designed, in situ shearometers placed in the bed atappropriate elevations to determine the time-dependence of the storage and loss moduli, G' and G", ofthe viscoelastic clay mixture under 1 Hz waves. As the inter-particle bonds of the space-filling, bedmaterial matrix weakened, the shear propagation velocity decreased measurably. Consequently, G'decreased and G" increased as a transition from dynamically more elastic to more viscous responseoccurred. These preliminary experiments have demonstrated the validity of the particular rheometrictechnique used, and the critical need for synchronous, in-situ measurements of pore pressures and modulicharacterizing bed rheology in studies on mud fluidization.This study was supported by WES contract DACW39-90-K-0010.(This document contains 151 pages.)

    Description: Turbidity is a measure of the clarity of water. Turbidity depends upon thescattering and absorption of light by suspended particles. The focus of this study wasto obtain quantitative measurements of turbidity in the nearshore zone, along withmeasurements of associated wave parameters and currents occurring naturally andduring a beach nourishment project. The objectives were to make quantitative andqualitative comparisons between natural events and those induced by the dredge andfill operations, as well as assess the long term effects of the nourishment, uponturbidity.In-situ measurements of turbidity and wave climate were obtained at two shorenormal sites off the coast of Hollywood, Florida, from January, 1990 to April, 1992.The beaches adjacent to the communities of Hallandale and Hollywood wererenourished during the summer of 1991. Thirty minute in-situ observations wererecorded in burst mode every four hours at a frequency of four hertz. Analysis of thedata resulted in descriptions of the wave climate as well as statistics of turbidity for each observation.

    Description: The mechanism by which fluid mud is formed by water wave motion over coastal andestuarine cohesive soil beds is of evident interest in understanding and interpreting themicrofabric of flow-deposited fine sediments in shallow waters, and hence the erodibilityof muddy beds due to hydrodynamic forcing. This study investigated water wave-inducedfluidization of cohesive soil beds composed of a 50/50 (by weight) mixture of a commercialattapulgite and a kaolinite in a laboratory flume. Temporal and spatial changes of theeffective stress were measured during the course of wave action, and from these changesthe bed fluidization rate was calculated. A previously developed hydrodynamic wave-mudinteraction model of the two-layered water-mud system was employed to study the natureand the degree of wave dissipation, in terms of energy dissipation rate, during the bed fluidizationprocess. By evaluating the mud rheological properties separately, a mud viscositymodel was developed, which was then used in conjunction with the wave-mud interactionmodel to obtain an effective sheared thickness of the bed resulting from wave action. Thisthickness, considered to be a representative of the fluidized mud thickness, was comparedwith the latter obtained from pressure measurements. Also, through this wave-mud modelthe relationship between the rate of fluidization and the rate of wave energy dissipationduring fluidization was examined. In general, for a given wave frequency, a larger wave fluidized the bed at a faster rateand to a greater depth than a smaller one. Furthermore, increased bed consolidation timedecreased the rate of fluidization due to increased mud rigidity. The rate of bed fluidizationwas typically greater at the beginning of wave action and decreased with time. Eventuallythis rate approached zero, while in some cases the wave energy dissipation rate approached aconstant value, which increased with wave height. As the fluidization rate approached zero,there appeared to occur an equilibrium value of the bed elevation, and hence a fluid mudthickness, for a given wave condition. During the fluidization process the bed apparentlylost its structural integrity by loss of the effective stress through a build-up of the excesspore water pressure. After wave action ceased, the bed structure exhibited recovery bydissipation of the excess pore water pressure.Further studies will be required in which the hydrodynamic model must be improved viaa more realistic description of mud rheology and relaxation of the shallow water assumption,and better pressure data must be obtained than in the present study. Nevertheless, thisinvestigation has been instructive in demonstrating relationships between the degree of mudfluidization, wave energy dissipation and bed consolidation time, and thus offers insight intoan important mechanism by which coastal and estuarine muds are eroded by wave action.

    Description: This thesis examines the historical shoreline response to inlet modifications and sealevel rise. Inlet modifications are considered to be the geographic stabilization and training(through the use of structures) of natural inlets and the creation and further modification ofartificial inlets. Shoreline response to natural and artificial processes must be understood inorder to predict the performance of the coastline. The tendency for creating and modifyinginlets increases as industry and population growth demands. Sea level rise is a natural processwhich cannot be controlled at this time. Current theoretical approaches to predictingshoreline response indicate that sea level rise and inlet modifications can cause substantialshoreline impact. Florida, with roughly a century of shoreline position and relative sea leveldata, provides a basis for examining past trends and comparing them with theory.The shoreline of Florida was found to be accreting with the greatest accretion alongthe east coast. Shoreline responses within the boundaries of the erosional influence of inletsdue to their creation and/or modification were examined for 19 inlets around the coast ofFlorida. The differences in the shoreline response before and after the initial modification ofeach inlet show the erosional strain that inlets apply on the nearby shoreline. The effect onshoreline response due to the human intervention (unnatural processes) of modifying inletswas isolated and examined. The shoreline response due to this "human intervention" was erosional, thereby showing the negative impact that modified inlets have on shorelines. Thisinduced erosion is responsible for the loss of roughly 21.6 million cubic yards of sand from theshoreline that is within the erosional influence of Florida's east coast inlets. Combining theshoreline changes due only to natural processes with sea level rise data allows for comparisonwith the commonly accepted Bruun Rule for shoreline response as a result of a changingsea level. This comparison and the effects of including a lag time between a rise in sea leveland a change in shoreline along the east coast of Florida during the last century show noagreement with the Bruun Rule and no correlation with a specific lag time.

    Description: A survey of coastal vegetation around Floridawas conducted during 1973 and 1974. Seventeen sites were selected and sampledusing the transect method to determine species occurrence, relative densities, andhabitat development and structure. Sites were sampled quarterly except where hightides prevented data gathering. Species occurrence was compared within andbetween sites using Sarensen's Index of Similarity (IS,) as a basis for determiningsimilarity of species inhabiting selected sites. Indices ranged from 4 to 61%, theformer representing only one plant common to two sites. Results showenvironmental factors acting upon species alter species composition in seeminglysimilar habitats. Instead of the term "community", the term "association" is used tobetter reflect the concept of a taxonomically unrelated group of plants occupying aparticular habitat. (Document has 40 pages.)

    Description: This faunal inventory of thePensacola Estuary, Florida, records 654 species of benthic and pelagic animals collectedsystematically from 1961 through 1963 and casually in other years. Samplingdates were correlated with approximate mid-points of spring rise and autumnal declineas well as annual extremes of water temperature. Biological sampling was coordinatedwith seasonal studies of hourly variation in salinity and water temperature duringsingle maximum amplitude tidal cycles recorded simultaneously at six stations alongthe salinity gradient. Data for each species include salinity of sampling station,habitat, season in which collected, and relative abundance.Predominant species were mollusks (184), annelids (91, chiefly polychaetes), arthropods(91, chiefly decapod crustaceans), and bony fishes (180). Spawning of aturbellarian, seven mollusks and 25 crustaceans, and breeding of horseshoe crabs arereported; limited data do not define duration of spawning or breeding seasons. Season.duration and intensity of setting of larvae of oysters, barnacles, bryozoans and serpulidworms in Santa Rosa Sound during 1962-63 and in Little Sabine Bay during1960-63 are also reported.

    Description: Savage, T. and J.R. Sullivan. 1978. Growth and Claw Regeneration of the Stone Crab,Menippe mercenaria. Fla. Mar. Res. Publ. No. 32.23 pp. Laboratory-maintained and feralcrabs were observed for incremental carapace width and major and minor claw growth.Morphometric relationships for male and female carapace width against length andcarapace width against major and minor claw sizes were derived. Only slopes of carapacewidth us. female major and male minor claws were not significantly different at the 95%confidence level. Feral normal male incremental growth exceeded that of normal femalesfor all parameters. Normal laboratory females possessed greater average carapace widthgrowth but less claw growth than did their male counterparts. All laboratory growth wasmore uniform but incrementally smaller than corresponding field growth. A hypotheticalgrowth plot constructed from incremental growth of several crabs indicated ages atattainment of sexual maturity and legal size to be 10 and 30 months. A pictorial descriptionof stone crab claw regeneration is presented. Minor claws realized greater regenerationafter one and two molts (73.5% and 96.5% of pre-autotomized sizes) than did major claws(68.6% and 89.0%). Intermolt interval of laboratory crabs increased with larger carapacewidth sizes. Claw loss shortened or lengthened duration of the intermolt period dependingupon whether the claw was removed shortly after a molt or later in the cycle. (Document has 27 pages.)
