Report providing results of hydrualic model investigations to test a new type of lock filling and emptying system to determine the final suggested construction for the Millers Ferry Lock in the Alabama River.

Partial abstract: Frequent dredging requirements and scouring at the foundation of Ocean City Inlet's south jetty resulted in a study to determine the source of the shoaling and scouring. The study concluded that sand was being transported northward along Assateague Island, through and over the south jetty, and deposited inside the inlet. The sand was then transported north by ebb currents where it encroached on the Federal navigation channel. A rehabilitation program was initiated to create a littoral barrier to eliminate the shoaling problem and to repair the scour hold. Three headland breakwaters were constructed to stabilize Northern Assateague Island. The site was selected as part of the Monitoring Completed Coastal Projects (MCCP) Program to determine how well the rehabilitation project accomplished its design purpose.

Partial abstract: "This report reviews the scope of a research effort initiated in 1974 at the U.S. Army Engineer Waterways Experiment Station with the objectives of (a) assessing the state of the art in geophysical cavity detection and delineation methodology and (b) developing new methods and improving or adapting old methods for application to cavity detection and delineation." This report discusses the geography, topography, site drilling tests, magnetic and microgravimetric surveys, and other information about the Medfor Cave site in Florida.

From abstract: This report summarizes the results of a comprehensive survey conducted to identify and characterize portable dredges available in the United States.

The main purposes of this study were to (a) obtain adequate test data to determine experimentally the vehicle cone index (VCI) for 50 passes for vehicles mounted with nonconventional tires and (b) use results of the field tests to develop a revised mobility index (MI) formula for self-propelled wheeled vehicles.

From introduction: The program's objective is to acquire information through intensive monitoring of coastal projects in an effort to improve project purpose and attainment, design procedures, construction methods, and operation and maintenance techniques.

Abstract: The model study was conducted to evaluate the characteristics of flow in the inlet channel, original sump, energy dissipator (saxophone outlet), and outlet channel and to develop practical modifications required for improving the hydraulic performance of the structure.

Final report regarding studies of weir jetties as an alternative for jetty design at tidal inlets. "The hydraulic model investigation was performed to study important design parameters for a weir jetty system including weir length, elevation, orientation with respect to the shoreline and the conventional portion of the jetty structure, tidal currents over the weir section, flow patterns in the vicinity of the weir section, sediment movement over the weir and effects of the weir jetty on accretion, and erosion upcoast of the jetty system" (abstract, para. 2).

"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).

Abstract: Kissimmee River structures S-65E, S-65D, and S-65B were reproduced in a 1:20 scale model in order to study ways of eliminating scour of the downstream riprap blankets by means of structural modifications of operating procedures.

"The purpose of this report is to present the results of an inspection performed at Biggs Army Airfield (BAAF), Fort Bliss, Texas, during January 1972. The inspection was limited to visual observations, and no tests were conducted on any of the pavement facilities. A layout of the airfield is shown in plate 1" (p. 1).

Results of model studies to determine the extent of destructive cavitation action (if any) in the stilling-basin elements at the Bluestone Dam in New River, West Virginia. The study also intended to develop means of correcting any conditions in the basin if needed.

Report on tests of permeability and triaxial of mass concrete as well as tests of permeability, pore pressure, and uplift in gravity dams.

"This report contains a summary of construction of procedures and field observations made during and after construction of Benbrook Dam, a brief review of the original design data, and comparisons of design predictions with performance data" (p. 1). It is part of a series to compare field experience and performance of existing structures with design predictions.

This report provides a summary and analysis of field observations and performance of the Tom Jenkins Dam in Ohio, compared with original design predictions.

The purpose of this manual is to describe and explain the use of the "Unified Soil Classification System" in order that identification of soil types will be on a common basis throughout the agencies using this system.

Report describing various kinds of soils and their characteristics, for use in constructing embankments and foundations: "The major properties of a soil proposed for use in an embankment or foundation that are of concern to the design or construction engineer are its strength, permeability, and consolidation and compaction characteristics. Other features may be investigated for a specific problem, but in general some or all of the properties mentioned above are of primary importance in an earth embankment or foundation project of any magnitude" (p. 1).
