Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...
Field Performance of a Soil Nail System in Loess
This paper presents data from measurements of a soil nail system constructed in loess soil in Pullman, Washington. The soil nail system is designed to retain a 39.2 ft (11.9 m) high excavation...
Evaluation of a 50-Year Old Barge Dock on the Missouri River
The installation of a large crane on an existing barge dock on the Missouri River in Kansas City, Kansas required an evaluation of the dock system stability. The dock was constructed of...
Underwater Foundations for a Jack-up Barge
Innovative underwater foundations were developed to provide a solid base for the legs of a large jack-up barge needed by General Dynamics to transport heavy components from Quonset Point,...
The Para?ba Do Sul Retrogradation and the Atafona Environmental Impact
This study is an attempt to explain the event which is presently occurring at the mouth of the Paraiba do Sul river and is causing a negative socio-economic impact on the Atafona population....
Water Quality Assessment in a Stochastic Stream Environment
Methodologies are presented within this article to aid in the quantification of the uncertainty in the management of stream water quality. Specifically, means are developed for: (1) establishing...
Trio of Microcomputer Models for Organic Chemical Transport in Rivers
Three microcomputer models have been jointly developed to provide tools to simulate the fate of organic chemicals in river systems. The three models offer a range of complexities and data...
Effect of Flow Conditions on Stream Reaeration Coefficients
Contrary to the findings of previous studies of channel-controlled stream reaches, it was found that, in four reaches of a small stream characterized by a series of pools and riffles,...
Stabilization of Critical Enclosed Natural Draft Ground Flares
This paper presents the results of an investigation evaluating the causes of and implementing a cost effective solution to combustion driven oscillations in six large natural draft flares....
Generating Instream Recreational Alternatives
A methodology combining an optimization model and a spreadsheet program is presented to assist resource managers in developing and evaluating instream recreational alternatives. Recreational...
Methodologies to Estimate Instream Benefits for Use in Water Allocation
In the 'utility valuation' approach, the recreational experience possible at given flow levels is examined to derive a utility that the resource provides to the...
Generation of Multiple Tier Instream Flow Requirements
Multiple tier scaling of instream flow requirements based on available water supply and reservoir storage state is proposed as a means of generating instream flow regimes. Rules for variable...
Southeastern Drought of 1988?A Federal Perspective
The drought that has plagued the Southeastern United States for most of the 1980's is continuing in two major river basins within the geographic boundaries of the South Atlantic...
Savannah River Basin Drought Contingency Planning
Beginning in 1986, and continuing through the present time, the worst drought in recent history created severe water shortage conditions over extensive areas of the southeastern United...
Behavior of Total Zinc in the Similkameen River
Multiple linear regression analysis was used to: develop equations that summarize the relationship between total zinc and a set of water quality characteristics measured in the Similkameen...
Flood Impact and Management of Levees in Tennessee
The construction of private levees is causing flooding and erosion problems along several tributary rivers in West Tennessee. The severity of these problems is recognized by the State...
Impact of Polders Upon Flood Stage of Atrai River
A mathematical model study, using System 11 model of the Danish Hydraulic Institute, is made to assess the impact of flood control polders upon flood level of Atrai River in Bangladesh....
Continued Development of the Columbia Basin Project?A Status Report
The Columbia Basin Project is located in central Washington State and encompasses approximately 1 million irrigable acres. Water from the project delivery system was first applied in 1952...
Proper Use of Effective Flow Boundaries
The determination of the appropriate effective flow boundaries is an important factor in the hydraulic modeling of the flow regime of a stream. It is especially critical in areas with...
Water Allocation in the Bay/Delta (California)
The California Water Resources Control Board is conducting hearings, over the period July, 1987 to 1991, to review beneficial uses of the water tributary to, within, and exported from...
