Shoreline Movements, Report 1: Cape Henry, Virginia, to Cape Hatteras, North Carolina, 1849-1980

From addendum: . Part 3 of Technical Report CERC-83-1 describes the general cartographic process used to produce the shoreline position digital data base and maps from which the attached set of 18 composite shoreline position map reproductions were made. The report also describes quality control methods, potential error sources, and probable ranges of error for this process.

Mission Bay Harbor, California, Design for Wave and Surge Protection and Flood Control: Hydraulic Model Investigation (open access)

Mission Bay Harbor, California, Design for Wave and Surge Protection and Flood Control: Hydraulic Model Investigation

Partial abstract: A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various south jetty extensions, and (c) diversion dikes on the middle jetty.

Cavity Detection and Delineation Research, Report 1: Microgravimetric and Magnetic Surveys: Medford Cave Site, Florida

Partial abstract: "This report reviews the scope of a research effort initiated in 1974 at the U.S. Army Engineer Waterways Experiment Station with the objectives of (a) assessing the state of the art in geophysical cavity detection and delineation methodology and (b) developing new methods and improving or adapting old methods for application to cavity detection and delineation." This report discusses the geography, topography, site drilling tests, magnetic and microgravimetric surveys, and other information about the Medfor Cave site in Florida.

Weir Jetty Performance: Hydraulic and Sedimentary Considerations: Hydraulic Model Investigation

Final report regarding studies of weir jetties as an alternative for jetty design at tidal inlets. "The hydraulic model investigation was performed to study important design parameters for a weir jetty system including weir length, elevation, orientation with respect to the shoreline and the conventional portion of the jetty structure, tidal currents over the weir section, flow patterns in the vicinity of the weir section, sediment movement over the weir and effects of the weir jetty on accretion, and erosion upcoast of the jetty system" (abstract, para. 2).
