Abstract: Prototype studies were conducted to measure pressures in the filling and emptying culvert system and to monitor various other parameters relating to the operation of the new John Hollis Bankhead Lock.

Abstract: This model study was conducted to evaluate the characteristics of inflow conditions into an existing pump sump that would result with increased discharge capacity due to installation of the three proposed pumps and to develop modifications, if needed, within the confines of the present sump to improve flow distribution to the pump intakes.

From abstract: Tests on the Chesapeake Bay hydraulic model were conducted to specifically investigate possible changes in the hydrodynamic characteristics of velocity, salinity, and tidal elevations associated with the proposed channel enlargements.

From abstract: Tests were conducted on a 1:40-scale model of Big Creek to investigate the hydraulic performance of a proposed floodway channel and a section of a modified channel.

From abstract: The Columbia Hybrid Modeling System was applied to the mouth of the Columbia River estuary to evaluate alternatives for reducing navigation channel maintenance dredging.

From abstract: The ultimate goal of numerous experiments is to develop the desired flow split for the design discharge of 14,600 cfs while maintaining acceptable water-surface elevations in the upstream channel.

From abstract: This report documents the laboratory model investigation of the lock filling and emptying system for lock addition planned for the Marmet Navigation Project.

"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."

This report summarizes the investigations of soil properties, aquatic biota, and wildlife held in the marshland and upland communities on dredged material behind a sandbag dike at Bolivar Peninsula, Galveston Bay, Texas.

This report summarizes habitat development activities at the Nott Island Upland Habitat Development Site in the Connecticut River near Essex, Connecticut, including aspects of engineering, botany, soils, and wildlife.

This report is Appendix A to the Buttermilk Sound marsh development summary report and presents the results of habitat development activities the marsh in Glynn County, Georgia. The activities were made between spring of 1975 and fall of 1977.

This report follows field investigations made to study the characteristics of turbidity plumes in the vicinity of open-water pipeline disposal operations.

Abstract: "Results of an investigation conducted to determine the engineering feasibility of using dredged material to expand an existing marshland area are presented. Dredged material obtained from maintenance dredging operations was found suitable for use as marsh substrate and site conditions were found adequate for construction of a containment facility. Factors evaluated in the study include site-specific feasibility of marsh expansion using dredged material, sizing of the demonstration area to meet water-quality and storage needs, preliminary design of the containment facility, procedures for the placement of dredged material, and identification of alternative construction methods, materials, and costs. Overall feasibility of marsh expansion was demonstrated and additional investigations were recommended for the project."

This report is the final report on the field investigations in Eaton's Neck Disposal Site, Long Island Sound.

This report summarizes collected data of soils from 45 sites meant to characterize the operational environments in dredged material containment areas in nine Corps of Engineer districts in the United States so that performance of low-ground-pressure vehicles operating in these areas could be predicted.

From abstract: "This report presents recommendations for proper investigation, design, and construction of retaining dikes to aid in ensuring that these dikes will be constructed with a minimum of problems and will serve their project requirements."

From preface: "This report presents a summary of studies conducted at Miller Sands Island, a tidal freshwater, dredged material disposal site in the Columbia River, Oregon. Studies were conducted from March 1975 to August 1977 to determine the feasibility of developing productive aquatic and terrestrial wildlife habitat on dredged material and to determine if development of wildlife habitat is a viable alternative to other dredged material disposal options."

This report is a compilation of reports made on the study of habitat development in Miller Sands Marsh and Upland Habitat Development Site in Columbia River, Oregon. This report provides data on birds, mammals, and terrestrial macroinvertebrates that were collected, analyzed, and compared with data from other regions of the United States.

From executive summary: "This report summarizes work done on the dynamics of the underground portion of some of the salt marsh plants along the Atlantic coast of the United States, the characterizations of soils in those plant stands, and experiments on the substrate selective properties of several of the plants."

This report follows a two-part study made to investigate the hydraulic regime and physical nature of bottom sedimentation in the vicinity of the mouth of the Columbia River where disposal of large quantities of dredged material that has occurred over the last several decades.

From preface: "This report presents the results of an investigation of factors influencing plant zonation and succession on salt marshes."

Abstract: "This report summarizes the importance of common species of salt marsh plants inhabiting wetlands of the eastern U.S. coast. An evaluation of the ecological significance of the plants is based on their rates of primary production, morality, and contribution of detritus to the estuarine dependent systems. The data are important in reaching decisions relative to the deposition of dredged material in these coastal wetland systems."

This report represents the investigations made by Work Unit 2A07 regarding the experimental deposition of dredged material on salt marshes.

From abstract: "This report presents a detailed discussion of he results obtained in a study conducted to evaluate the release of polychlorinated biphenyls (PCB's) during open-water disposal of contaminated dredged material in Elliot Bay, Puget Sound, Washington."
