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."

"The problem of rock erosion in unlined emergency spillway channels is described in this first-of-a series report. Recent CE and non-CE case histories which illustrate the potentially hazardous impacts of excessive erosion in discharge channels are described as are the various factors controlling erosion and other responses to emergency spillway overflow. Research programs designed to improve geotechnical capabilities with respect to selection of cost-effective preventive and remedial measures in discharge channels where the risk of excessive erosion appears high are also discussed" (abstract, para. 1).

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."

From introduction: This report presents the results of a movable-bed model investigation concerned with the development of plans for the improvement of the Dogtooth Bend reach of the Mississippi River.

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."

This report provides information about slope stability problems which will arise if a new canal is excavated through the types of weak shale encountered along the present Panama Canal. It includes a discussion about the general problem and possible approaches, a review of previous experience, and a description of the new study.

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.

Partial summary: "Soil moisture, soil strength, and other relevant data were collected in Thailand during two wet seasons and one dry season for use in the development of methods to predict soil trafficability for off-road ground contact vehicles in Southeast Asia. Data were collected at 75 test sites distributed in eight geographic areas which had differences in soils, weather regimes, terrain, and land use" (p. xi).

From abstract: This report describes a study of coastal processes along the Atlantic Coast from Sea Bright to Ocean Township, New Jersey. Predictive tools were developed and a data analysis made to assist in evaluation and implementation of comprehensive shore protection plans for this highly utilized stretch of coastline.

Appendix containing supplementary data from an experiment conducted to examine variance in physical and chemical variables made at a naturally occurring marsh and an artificially made experimental marsh. It accompanies a report on habitat development field investigations of the Windmill Point Marsh Development Site, James River, Virginia.

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 summary report is part of a series documenting the field site investigations conducted by the Habitat Development Project initiated to study for more definitive information on the environmental impact of dredging and dredged material disposal operations. This report documents tasks such as: (a) Effects of Marsh and Terrestrial Disposal, (b) Marsh Development, (c) Terrestrial Habitat Development, (d) Aquatic Habitat Development, and (e) Island Habitat Development.

This report discusses a study to identify materials and techniques to repair monolith joints, a common location for deficiencies in dams and locks. It also identified areas for further investigation to supplement existing technologies.

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.

Appendix containing calculations of the mass transport of chemical components and the error terms used to accompany the second volume of a report on the environmental impacts of marsh development with dredged material as part of a study on the feasibility of marsh development using dredged material at the Windmill Point Marsh Development Site, James River, Virginia.

Summary: "This appendix presents the procedures for digital implementation of the segmented tire model, developed in the basic report for an analog computer. Two procedures are required: (a) determination of the segment spring coefficient from measured load-deflection test results, and (b) computation of the resultant force vector transmitted to the axle. Digital programs for both procedures were written in Fortran IV for a GE-420 system, and are included" (p. xi).

Appendix containing an assessment of vegetation on a dredged material island located near Windmill Point in the freshwater tidal reach of the James River. It accompanies a report on habitat development field investigations of the Windmill Point Marsh Development Site, James River, Virginia.
