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.

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).

From abstract: This report summarizes the results of a comprehensive survey conducted to identify and characterize portable dredges available in the United States.
