Material Property Investigation for Project Middle Gust, Events 1, 2, and 4: Report 1, Subsurface Exploration and Laboratory Test Results

Description: This report documents the results of a site investigation conducted to support free-field ground shock calculations and field operations for Project MIDDLE GUST, Events I, II, and III. The site is characterized by a 6- to 9-ft-thick section of sandy clay (CL) and clayey sand (SC) overburden overlying almost 500 ft of clay shale of the Pierre Formation which overlies older sedimentary rocks. A perched groundwater table in the overburden, approximately 4 ft below the ground surface, is fed by water from the Colorado Canal, which borders the site on three sides.

Weir Jetty Performance: Hydraulic and Sedimentary Considerations: Hydraulic Model Investigation

Description: 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).

Mission Bay Harbor, California, Design for Wave and Surge Protection and Flood Control: Hydraulic Model Investigation

Description: Partial abstract: A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various south jetty extensions, and (c) diversion dikes on the middle jetty.

A Field Test of Selected Insects and Pathogens for Control of Waterhyacinths, Report 1: Preliminary Results for the 1975-76 Season

Description: "During the growing season of 1975, a field experiment was initiated on Lake Concordia, Louisiana, to test the potential effectiveness of selected organisms as control agents against waterhyacinths, Eichhornia crassipes (Mart.) Solms. [...] This report describes the experiment, presents the collected data, and summarizes the observations. Statistical analyses and interpretation of the data are also presented" (abstract).

A Technique for Quantifying Forest Stands for Management Evaluations

Description: "In this study, a system for describing the three-dimensional geometry of trees and stands is presented. The system consists of two survey instruments, a theodolite and transit, and basic triangulation principles. A spotting laser has recently been added to the system to facilitate the spotting of the tree nodes to be surveyed" (p. ix). Results show significant differences in tree productivity as a result of fertilization and changes in heights, bole diameters, etc.

Dynamics of Wheeled Vehicles, Report 1: A Mathematical Model for the Traversal of Rigid Obstacles by a Pneumatic Tire, Appendix B: Digital Implementation of Segmented Tire Model

Description: 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).

Expedient Reinforcement of Concrete for Use in Southeast Asia: Report 1: Preliminary Tests of Bamboo

Description: "This report summarizes the preliminary results of a current U. S. Army Engineer Waterways Experiment Station (WES) study of the feasibility of using bamboo as an expedient reinforcement for temporary, reinforced concrete structures. The report contains an extensive review of the literature, a description of the test procedures, results of an investigation of the most important engineering properties of bamboo, descriptions of tests of 26 bamboo-reinforced structural elements (20 simply supported beams with 6-ft (1.83-m) spans, and 6 simply supported two-way slabs of varying length, width, and depth), and conclusions and tentative recommendations for the design of bamboo-reinforced structures" (p. xiii).

Physical Hydraulic Models: Assessment of Predictive Capabilities; Report 1: Hydrodynamics of the Delaware River Estuary Model

Description: Partial abstract: The purpose of this study is to define the reliability with which results of tests conducted in a physical model of the Delaware River Estuary can be used to predict the effects of modifications to the estuary. The Delaware River model at the Waterways Experiment Station was used to conduct tests to predict the effects of the navigation channel enlargement between Philadelphia and Trenton, and the results of the tests are compared with subsequent prototype data to determine the accuracy of the model predictions.

Marysville Lake Hydrothermal Study: Report 2

Description: Partial abstract: "This study was conducted to determine the effect that the proposed Marysville Lake pump-storage hydropower (2250-mw power plant) project would have on downstream water temperatures. A one-dimensional numerical model was used for simulation and prediction of temperatures within and downstream of Marysville Lake. Two physical hydraulic models were used for study and description of the hydrodynamic response of the project. Information from the physical models was necessary to determine coefficients used by algorithms within the mathematical model."
