Partial abstract: "The current state of the art of design, fabrication, and erection techniques of various prefabricated elements for concrete structures are reviewed. Included are precast concrete highway bridges, logging bridges, railway bridges, piles, culverts, pipes, floating structures, and field fortifications. The structural properties, advantages, and disadvantages of various elements and systems are discussed."

Partial abstract: "The results of analytical studies are presented in which (i) the SAP IV elastic finite-element (FE) code was used to perform modal analyses for a rectangular structure in vacuo and embedded in different backfill materials, and (2) a series of dynamic and static two-dimensional (2D), plane-strain, FE, structure-medium interaction (SMI) code calculations were performed using the HONDO code."

This report describes a study to measure redistribution in sand due to cyclic shear and gyratory shear including descriptions of the apparatus and equipment, with shop drawings; test procedures; test results; and discussion of the study and findings.

"This report summarizes published geotechnical properties of raw and retorted oil shales from the Green River Formation. Basic physical properties including gradation, specific gravity and Atterberg limits and engineering properties including compaction, permeability, settlement, soundness, and strength are summarized and discussed. Where appropriate, conclusions are drawn about the suitability of retorted oil shales as a geotechnical construction material. Appendix A discusses three retorting processes used to extract oil from oil shale" (abstract, para. 2-3).

Report regarding analysis of a lock and dam in the Arkansas River. "The purpose of this study is to take 8 years of instrumentation data from Lock No. 5 and report it in such a manner that it can be used later in other studies, such as a finite element analysis. Included is a discussion of the quality of the data and a brief comparison of measured values with design cases for several soil-structure interaction cases" (p. 5).

This report documents the dredging practices, reclamation methods, and environmental effects of dredging in western Europe that were studied with emphasis on their relevance to the Dredge Material Research Program (DMRP).

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.

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

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.

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."

This report follows the Windmill Point marsh habitat development project. The marsh was constructed in the James River between November 1974 and February 1975, then studied for benthic invertebrates, fish, wildlife, plants and soil characteristics from the summer of 1976 to fall of 1977.

From preface: "This report contains the results of investigations of the chemical and sedimentological characteristics of the James River Artificial Habitat Development Site and a reference marsh near Windmill Point, Virginia. Studies were conducted in the channel before dredging and during site construction as well as at specific time intervals after marsh development."

From preface: "This report summarizes the results of a comprehensive investigation of the impact of open-water dredged material disposal by barges in Elliot Bay, a portion of Puget Sound Estuary, Washington."

This study was funded by NAPEN to aid in evaluating proposed modifications. Plans of improvement for New Jersey inlets and beaches were presented by NAPEN in a Navigation and Cooperative Beach Erosion Control Study.

The following report describes work done by the Marine and Freshwater Ecology Branch, Corvallis Environmental Research Laboratory (CERL), Environmental Protection Agency (EPA), Corvallis, Oregon. The study was conducted on the chemical and physical effects of open-water disposal of dredged material from the Duwamish River into Elliot Bay, Washington.

This report summarizes the results of investigations of the distribution of colonial seabirds and wading birds on New Jersey dredged material islands, of vegetation distribution and succession on dredged material islands, and of the interactions of vegetation and birds on dredged material islands.

The information provided in this report follows the investigations of the use of dredged material islands made by colonial nesting seabirds and wading birds in Texas initiated in October 1976.

The following report documents the habitat relationships at 24 selected natural and dredged material colonial bird nesting sites and identifies the species and population sizes of all colonial nesting birds of the U.S. Great Lakes of up to 1.6 km inland.

From preface: "This report presents a summary of results of a 2.5-year field investigation (March 1975 to November 1977) of the feasibility and impact of developing marsh and upland habitat on dredged material at a site located at Bolivar Peninsula, Galveston Bay, Texas. The report summarizes baseline information derived before habitat development operations and results of post-development operations."
