Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...
The Role of Multiple Level Hydrologic Analysis in Watershed Management?A Case Study in Trinidad
An accurate estimation of peak flood flows and its correlation with existing and future land use are basic requirements for the scientific management of Watersheds. An accurate estimation...
Some Aspects of Analysis and Prediction of Subsidence
A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions...
Electric Utility Noise Emissions
Environmental regulations require that impact statements for new electric utility and industrial power plants include an evaluation of noise emissions. Variations in equipment sound power...
Design and Operating Rules for Reservoir Storage to Offset Future Consumptive Use
The Washington Metropolitan Area (WMA) relies largely on the Potomac River for water supply. After many years of study, a coordinated regional operating plan was adopted by the water supply...
Quantifying Social and Environmental Objectives
Over the past decade, there have been great improvements in economic and multiobjective techniques for quantifying social and environmental objectives in water resources planning. Nevertheless,...
Water Use Forecasting and Evaluating the Effects of Conservation Measures
The City of Austin, Texas, instituted mandatory restrictions on water use during a summer drought in 1984 when water use levels beyond 150 million gallons per day stressed the city's...
Modelling Complex Water Distribution Systems
A program previously used for the analysis of hundreds of water distribution systems was successfully modified to provide the features needed for the extended simulation of large complex...
A Methodology for Optimal Network Design
A methodology is developed to optimize the design of water distribution networks using reduced gradient techniques with a network simulator. The problem is reduced in complexity by incorporating...
Forecasting Water Use: A Tutorial
In spite of 4,000 years of public water supply system construction, designs have been customarily based on forecasts of future water use only during the last 100 years. Choices among available...
Forecasting Demand for Urban Water
The purpose of this study is to assess current water use forecasting practice in the US Army Corps of Engineers and to recommend additional approaches which best satisfy current requirements....
Evaluating Water Policy Options by Simulation
Computer simulation models are used to predict the effects of three sample water policy decisions on selected conjunctive water use/sustained groundwater yield strategies for the Arkansas...
Direct Filtration of High Turbidity Water Using Contact Flocculation
It is shown that the system of bed contact flocculation followed by standard dual media filters provides a viable alternative to both conventional as well as direct filtration, particularly...
Town Lake: An Environmental Impact Assessment
The City of Dallas, Texas, had little experience with environmental impact assessments of major capital improvements projects. Yet when deciding whether to build a 110,000,000 urban lake,...
Evaluation of Point-of-Use Treatment Devices
The contamination of drinking water is a matter of concern to many communities and people. Small community water systems and individual residences supplied by private wells face severe...
Denver's Dual Utilization Sludge Management Plan
The Metropolitan Denver Sewage Disposal District No. 1 (District) has adopted a Dual Utilization approach to sludge management. This technique uses composting during periods of inclement...
Conveyance Losses Due to Reservoir Releases
Three natural streams in Wyoming were studied in order to estimate incremental conveyance losses associated with incremental increases in stream flow. For each study area, all surface...
Use of Drainage Control to Minimize Potential Detrimental Effects of Improved Drainage Systems
Improved drainage systems are necessary on many soils for sustained agricultural production. However, there are several drainage system designs which can be utilized to satisfy agricultural...
Trends in Irrigation Water Use?Texas Rice Belt
In the Rice Belt along the Texas Gulf Coast, where stress on water resources is increasing, federal, state, and local specialists are conducting a 5-year examination of irrigation. Measured...
Progress in Controlling Subsidence in the Houston Area
The withdrawal of large quantities of groundwater in Harris and Galveston counties of Texas has resulted in a critical subsidence problem, especially in the low lying areas along the coast....
