Geotechnical Properties of Oil Shale Retorted by the PARAHO and TOSCO Processes

Description: 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."

Repair of Waterstop Failures: Case Histories

Description: This report discusses case studies of failures in waterstops that prevent water passage through the monolith joints of concrete dams and locks. "The primary objective of this study was to identify materials and techniques which have been used in repair of waterstop failures. Also, based on a review and evaluation of current practices, a secondary objective was to identify those areas where research is needed to supplement existing technology" (abstract).

Geological Reconnaissance of the Sulphur River and Cypress Creek Basins, Texas

Description: This report is concerned with that part of the Texas Water Project located in the Cypress Creek and Sulphur River Basins and within the New Orleans District (NOD) of the U. S. Army Corps of Engineers. The geological reconnaissance reported herein was performed for the NOD to provide a basis for estimating costs and determining the feasibility of construction of 5 dams and reservoirs, 1 tunnel, 15 pump stations, and about 110 miles of transmission channel and the enlargement of 2 existing reserv… more

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

Description: 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 ar… more

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

Description: 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."
