    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: Hurricane Hugo hit U.S. Mainland on September 21, 1989just north of Charleston, South Carolina. It was billedas the most costly hurricane on record. The loss on themainland alone exceeded 7 billion dollars, more than15,000 homes were destroyed and the loss of livesexceeded forty.This article documents one aspect of the multi-destructionscaused by the hurricane - the water anderosion damage on water front or near water frontproperties. A general damage survey was given first,followed by assessment on the performance of variousengineered and non-engineering structures, on the majorfactors contributing to failures. Conclusions were thendrawn with recommendations for future improvement. (26pp.)

    Description: Seawall design on the open coast is an often overlooked problem inthe State of Florida as well as other areas of the South Atlantic and GulfCoasts. Escoffier [1] mentions numerous seawall failures and improperdesign considerations along the Mississippi Gulf Coast which were exposedby hurricanes after the seawalls were built. It is hoped that this bulletin, along with Reference 3, will provide agood starting place for those involved in technical design and constructionsupervision aspects of seawalls.

    Description: This study was carried out to examine the effects of seawalls on the adjacentbeach by three dimensional model test. The results obtained from model test wereanalyzed in terms of volumetric changes and shoreline and hydrographic change toquantify the effects of seawalls.The experiments were carried out in the wave basin of Coastal and OceanographicEngineering department, University of Florida. A model seawall was installedon the test beach (19mxl4m) which was initially molded into equilibriumshapes. During the test, hydrographic surveys were conducted at regular time intervals.The main variable in the experiment is the wave angle. Cases both withand without seawall were tested. (141pp.)

    Description: Vacuum-packed Yellowfin tuna steaks were individually frozen in either liquid Freon or in an air storage freezer, and evaluated for keeping quality after 1, 3, and 6 months of frozen storage (-27OC). The resulting freezing rates were used to project the economic feasibility of a small scale commercial processing plant. Regardless of freezing method the vacuum-packed steaks demonstrated keeping quality comparable to fresh control samples handled as in normal distribution channels. The estimated cost to manufacture allowed sufficient profit at competitive selling prices to generate a rate of return of 132%. This would pay back the estimated cost of plant and equipment in less than one 6-month season of operation at full capacity (16pp.)

    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 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.)
