    An Easy-to-Construct Automated Winkler Titration System (2021)
    Monterey Bay Aquarium Research Institute | Moss Landing, CA

    Publication Date: 2021-07-11
    Description: The instrument described in this report is an updated version of the high precision, automated Winkler titration system described by Friederich et al.(1984). The original instrument was based on the work of Bryan et al. (1976) who developed a colorimetric endpointdetector and on the work of Williams and Jenkinson (1982) who produced an automated system that used this detector.The goals of our updated version of the device described by Friederich et al. (1984) were as follows:1) Move control of the system to the MS-DOS environment because HP-85 computers are no longer in production and because more user-friendly programs could be written using the IBM XT or AT computers that control the new device.2) Use more "off the shelf" components and reduce the parts count in the new system so that it could be easily constructed and maintained.This report describes how to construct and use the new automated Winkler titration device. It also includes information on the chemistry of the Winkler titration, and detailed instructions on how to prepare reagents, collect samples, standardize and perform the titrations (Appendix I: Codispoti, L.A. 1991 On the determination of dissolved oxygen in sea water, 15pp.). A disk containing the program needed to operate the new device is also included. (pdf contains 33 pages)

    Description: This report responds to the 1986 Beaches Bill which, in recognition of thepotential deleterious impact on Florida's beaches of inlets modified for navigation,mandated a study of those inlets with identification of recommended action to reducethe impacts. This report addresses west Coast inlets; East Coast inlets are thesubject of a companion report.There are 37 inlets along that portion of Florida's West Coast commencing fromPensacola Bay Entrance to Caxambas Pass at the south end of Marco Island. Compared tothose on the East Coast, most West Coast inlets have not had the deleterious effectson the adjacent beaches, yet all modified inlets without proper management have thepotential of impacting unfavorably on the adjacent shorelines. Moreover, at presentthere is interest in opening three West Coast entrances which either have been openin the past (Midnight Pass) or which have opened occasionally (Navarre Pass andEntrance to Phillips Lake).A review of inlets in their natural condition demonstrates the presence of ashallow broad outer bar across which the longshore transport Occurs. These shallowand shifting bar features were unsuitable for navigation which in many cases has ledto the deepening of the channels and fixing with one or two jetty structures. Inlets in this modified state along with inappropriate maintenance practices have thepotential of placing great ero$ional stress along the adjacent beaches. Moreover.channel dredging can reduce wave sheltering of the shoreline by ebb tidal shoals andalter the equilibrium of the affected shoreline segments. The ultimate in poor sandmanagement practice is the placement of good quality beach sand in water depths toogreat for the sand to reenter the longshore system under natural forces; depths of 12ft. or less are considered appropriate for Florida in order to maintain the sand inthe system.With the interference of the nearshore sediment transport processes by inletsmodified for navigation, if the adjacent beaches are to be stabilized there must bean active monitoring program with commitment to placement of dredged material ofbeach quality on shoreline segments of documented need. Several East Coast inletshave such transfer facilities; however. the quantities of sand transferred should beincreased. Although an evolution and improvement in the technical capability tomanage sand resources in the vicinity of inlets is expected, an adequate capabilityexists today and a concerted program should be made to commence a scheduledimplementation of this capability at those entrances causing greatest erosionalstress on the adjacent shorelines.A brief summary review for each of the 37 West Coast inlets is presentedincluding: a scaled aerial photograph, brief historical information, several itemsrelated to sediment losses at each inlet and special characteristics relevant toState responsibilities. For each inlet, where appropriate, the above infor~tion isutilized to develop a recommenced action. (PDF has 101 pages.)

    Description: Inlets are common coastal features around the world. Essentially aninlet connects a lagoon, a bay or an estuary to the ocean (or sea), and theflow through the inlet channel is primarily induced by the tidal rise andfall of water level in the ocean. When speaking of the hydraulics of an inlet,one is interested mainly in determining the flow through the inlet andthe tidal variation in the bay, given the following:(1) Inlet geometry(2) Bay geometry(3) Bottom sediment characteristics in the inlet(4) Fresh water inflow into the bay (and out throughthe inlet)(5) Ocean tide characteristicsA combination of all these factors can produce a rather complex situation.

    Description: The framework of sediment budget concepts provides a formalized procedureto account for the various components of sediment flux and the changes ofvolume that occur within a given region. Sediment budget methodology can beuseful in a number of coastal engineering and research applications,including: inferring the amount of onshore sediment transport for a nearshoresystem that contains an "excess of sediment", determining sediment deficits todowndrift beaches as a result of engineering works at navigational entrances,evaluating the performance of a beach nourishment project, inferring thedistribution of longshore sediment transport across the surf zone, etc.This chapter reviews briefly the governing equations for sediment budgetcalculations, considers various measurement and other bases for determiningthe sediment flux components necessary to apply the sediment budget conceptand finally for illustration purposes, applies the sediment budget concept toseveral examples.

    Description: A fixed-bed hydraulic model of Jupiter Inlet, Florida, wasconstructed for the purpose of testing measures designed to remedyproblems of sediment erosion and deposition in the inlet area. Bothtide-induced flows as well as waves were simulated in the model whichwas built on an undistorted scale of 1:49. Model verification was basedon prototype measurements of waves, tides and currents. Results havebeen interpreted in terms of the influence of various proposed remedialschemes on flow velocity magnitude, distribution and wave height atvarious locations within the study area. A stability parameter has beenutilized for evaluating the degree of sediment erosion or deposition ata given location.Various structural solutions were examined in the model. It isproposed that, in the initial phase of solution implementation, sedimentremoval/nourishment methods be used primarily to mitigate the existingproblems. New structures, as per model test results, should beinstalled under subsequent phases, only if sediment managementprocedures do not prove to be adequate. The currently followedprocedure of periodic sand trap dredging may be extended to include thenew dredging/nourishment requirements. (PDF contains 245 pages.)
