Feasibility Study for Dyke Marsh Demonstration Area, Potomac River, Virginia
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."

Primary Productivity of Minor Marsh Plants in Delaware, Georgia and Maine
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."

Geotechnical Properties of Oil Shale Retorted by the PARAHO and TOSCO Processes
Partial abstract: "Waste disposal schemes using spent shale in embankments require a thorough knowledge of its geotechnical engineering properties for environmentally safe disposal. In this context, the objective of this laboratory investigation was to determine the physical properties, geotechnical properties, and composition of spent oil shale retorted by the PARAHO and TOSCO processes."
