Kern County Water Agency?1991 Emergency Ground Water Recovery Program
The 1991 Emergency Ground Water Recovery Program was conceived and implemented by the Kern County Water Agency to deliver water to four water districts to save permanent crops. The Program...
Sustained Yield of the Provo Groundwater Basin
The sustained yield of the Provo Groundwater Basin has been determined by a correlation analysis of the change in groundwater levels with the April-October stream flow at the mouth of...
Distribution of Stable Isotopes in Ground Water in the Rialto-Colton Basin, California
Since 1982, imported water originating in the Sierra Nevada has been used to recharge the Rialto-Colton ground-water basin, about 100 km east of Los Angeles. Stable isotopes of oxygen...
Soil Treatment of Food Processing Wastewater
Wastewater from food processing contains a large oxygen demand. Most food processing wastewater requires primary treatment to remove some solids and secondary treatment to oxidize oxygen...
Distribution and Mobilization of Dissolved Selenium in Ground Water of the Irrigated Grand and Uncompahgre Valleys, Western Colorado
Distribution of dissolved selenium in ground water of the irrigated Grand and Uncompahgre Valleys is affected by the aqueous geochemical environment of the shallow ground-water system...
Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...
Streamflow Depletions Resulting from Ground Water Transfers
An application to move the point of diversion of a quasi-municipal ground water right from about 4.8 km to a second well about 0.3 km from a river channel was made in the Reno/Sparks,...
Well Response in a Leaky Aquifer and Computational Interpretation of Pumping Tests
An analytic solution is derived describing flow in a horizontal confined leaky aquifer of infinite extent around a fully penetrating well of negligible storage capacity. The differences...
Concentration History During Pumping from a Leaky Aquifer with Stratified Initial Concentration
Analytical and numerical solutions are employed to examine the concentration history of a dissolved substance in water pumped from a leaky aquifer. Many aquifer systems are characterized...
An Overview of Methods to Delineate Capture Zones of Pumping Wells
Rainfall over the surface area of an unconfined aquifer, which contributes flow to a pumping well under Dupuit conditions, was estimated. Using a two-dimensional analytical model with...
Coping with Agricultural Shortages
Coping with agricultural shortages occupies most of the time and energy of the Kern County Water Agency (Agency). The Agency's participation in the State Water Project (SWP) originated...
Designing Self-Cleaning Wet Wells for Wastewater Pumping
Guidelines for the design of self-cleaning wet wells for variable speed pumps are given. The progress of research on the design of wet wells for constant speed pumps, including submersible...
Modeling Saltwater Intrusion Control Measures in the West Coast Basin
In the 1960's and 1970's the West Coast Basin Barrier was constructed to protect tha major coastal groundwater basin from further salt water intrusion, which had been occurring as a result...
An Optimal Parameter Estimation Model for Groundwater Resource Management
An optimal parameter estimation model is developed to identify the locations of wells, to determine pumping magnitude, and to calculate transmissivity coefficients in a confined aquifer...
Self-Cleaning Wet Wells: Definition and Design
Design guidelines for self-cleaning wet wells with variable speed pumps are given and the progress of research at Montana State University and ENSR Consulting and Engineering concerning...
Recent Developments in Safety Research from the Gas Research Institute
Recent developments in Safety Research, as supported by the Gas Research Institute (GRI), have consisted primarily of hardware-oriented applications to various gas industry safety operations....
Gas Pipeline Fitness-for-Service Investigation
A delta reclamation district's plan to add significant fill on their levee caused great concern for the integrity of a critical PG&E 22-inch (559 mm) gas transmission line which...
Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...
Cleaning Up in the Former Soviet Union
As they negotiate with authorities in Russia, Azerbaijan, Kazakhstan and other former Soviet Republics, Western companies�including many of the big oil and natural-resources firms�are...
Letter from Oman
The bonanza days of the 1980s are over, but the oil-rich sultanate continues to be a rewarding, if challenging, market. Oil remains a focus of investment, and the government is planning...
