Rehabilitation of the South Jetty, Ocean City, Maryland

Description: Partial abstract: Frequent dredging requirements and scouring at the foundation of Ocean City Inlet's south jetty resulted in a study to determine the source of the shoaling and scouring. The study concluded that sand was being transported northward along Assateague Island, through and over the south jetty, and deposited inside the inlet. The sand was then transported north by ebb currents where it encroached on the Federal navigation channel. A rehabilitation program was initiated to create a littoral barrier to eliminate the shoaling problem and to repair the scour hold. Three headland breakwaters were constructed to stabilize Northern Assateague Island. The site was selected as part of the Monitoring Completed Coastal Projects (MCCP) Program to determine how well the rehabilitation project accomplished its design purpose.

Prototype Evaluation of Bay Springs Lock Tennessee-Tombigbee Waterway, Mississippi: Hydraulic Model Investigation

Description: From abstract: Prototype tests were conducted to comprehensively evaluate the performance of the 84-ft-lift Bay Springs Lock. The evaluation included analysis of the operating characteristics and hydraulic efficiency of the lock as well as a comparison of the physical and analytical model results with the prototype.

Isabella Dam Spillway, Kern River, California: Hydraulic Model Investigation

Description: Abstract: "Tests were conducted on a 1:50-scale model of Isabella Dam Spillway to determine the adequacy of proposed spillway, dam, and channel improvements. The model reproduced an area of the reservoir 800 ft wide by 1,100 ft long, the spillway, and the entire length of the exit channel. Unsatisfactory flow conditions were observed in the vicinity of the spillway crest due to approach conditions to the spillway. Large cross waves, present in the exit channel just downstream of the spillway, resulted in occasional overtopping of the right wall. A grouted rock dike that provided satisfactory flow conditions at the spillway and downstream throughout the exit channel was placed adjacent to the existing spillway approach wall."

Chemical and Biological Characterization of Black Rock Harbor Dredged Material

Description: "This is one in a series of scientific reports documenting the findings of studies conducted under the Interagency Field Verifications of Testing and Predictive Methodologies for Dredged Material Disposal Alternatives (referred to at the Field Verification Program or FVP). This program is a comprehensive evaluation of environmental effects of dredged material disposal under conditions of upland and aquatic disposal and wetland creation."

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

Description: 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

Description: 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

Description: 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.

Large-Scale Operations Management Test of Use of the White Amur for Control of Problem Aquatic Plants, Report 2: First Year Poststocking Results, Volume 2: The Fish, Mammals, and Waterfowl of Lake Conway, Florida

Description: Abstract: "Fish, waterfowl and wading birds, and aquatic mammal populations on Lake Conway were surveyed for 1 year after the introduction of the herbivorous fish, white amur (Ctenopharyngodon idella). Low water levels reduced littoral zone area, which lead to stunted panfish and poorer condition of largemouth bass. Vegetated samples supported more diverse fish populations than beach sites. White amur and migratory waterfowl consumed the same plant foods; continued reduction of submerged plants by white amur may adversely affect overwintering waterfowl populations. Aquatic mammals were influenced by removal of vegetation due to shoreline development."
