Application of a Water Budget for Instream Flows
A portion of a water supply reservoir can be dedicated to supplying instream flows. This subreservoir is operated to provide instream fish habitat below the reservoir when releases to...
Multidisciplinary Hydrologic Investigations at Yucca Mountain, Nevada
Future climatic conditions and tectonic processes have the potential to cause significant changes of the hydrologic system in the southern Great Basin, where a nuclear-waste repository...
Water Erosion Prediction Project (WEPP) Watershed Model: Hydrologic and Erosion Calculations
The Water Erosion Prediction Project (WEPP) watershed model is a distributed continuous simulation model developed to compute the spatial and temporal distribution of erosion and deposition...
Supplemental Irrigation by Runoff Farming: An Economic Assessment
A simulation model was used to evaluate the economic potential for using runoff farming techniques for growing grain sorghum at two locations in Texas. The results show that the yearly...
Upgrading of the Orange Cove Irrigation District Water Distribution System
The Orange Cove Irrigation District covers about 28,000 Acres in the Central Valley of California. It is supplied from the Friant-Kern Canal. A semi-closed low pressure pipeline system...
Comprehensive Management of a Sole-Source Aquifer in Central Texas - A Model for Coping with Urban Development in Hydrologically Sensitive Areas
In the developing San Antonio/Austin area of central Texas, the Edwards Aquifer is highly vulnerable to contamination resulting from development. The Texas Water Commission (TWC) strives...
The Use of Wholesale Water Rates to Encourage the Groundwater Conjunctive Use
The availability and price of imported Colorado River water were critical components to the development of groundwater management programs in Southern California. Economical imported water...
The Colorado River Water Rights: Back to the Future
A discussion about tomorrow's projected water shortages in California and efforts to meet the anticipated demands through the Colorado River supply requires at least a brief...
Central Valley Project Operations
The Federal Central Valley Project (CVP) utilizes the water supply and storage regulated by the CVP's four major northern California reservoirs, Clair Engle, Whiskeytown,...
Future Expansion of the State Water Project
Measures currently underway by the California Department of Water Resources will result in water transfer enhancements to the State Water Project. Water banking facilities, in the form...
Expanding Groundwater Production in Southern California
The incentive to achieve greater conjunctive use in Southern California has been provided by the Metropolitan Water District of Southern California through a special pricing mechanism...
A Reservoir Yield Evaluation in an Arid Climate
Yield calculations rarely can be more accurate than roughly plus or minus twenty percent. The same uncertainty is dramatically greater in arid climates where the average annual runoff...
Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...
Mt. Elbert Pumped Storage Trashrack Failure
The failure of three trashrack sections for unit 2 at the suction-draft tube intake occured after one year in service. However, the trashracks for unit 1 had five years of service with...
On the Problem of Sediment Deposition in Large Reservoirs
Sediment deposition and its accumulation in a large reservoir depends on the inflow and reservoir storage content, respectively. This fact is used to model the cumulative deposition of...
Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...
A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...
Design of Fiberglass Reinforced Plastic Underground Storage Tanks
The purpose of this paper is to discuss the design and construction techniques of fiberglass composite underground storage tanks. The scope of this paper is limited to the straight shell...
Let the Buyer Beware
As recently as the 1970s, state highway agencies blindly purchased land for projects without much concern for hazardous waste. But that changed in 1980 with Superfund legislation, specifically...
Instrumenting for Eternity (Almost)
Prendergast describes the safety features and instrumentation for a low level radioactive waste disposal facility planned for Illinois. Federal law requires that each state or group of...
