Overview of EPRI'S Solid Waste Environmental Studies
The Electric Power Research Institute (EPRI) initiated a comprehensive research project in 1983 with the long-term goal of improving and validating methods for predicting the fate of chemicals...
Ground-Water Drainage to Surface Mines Refined
Changes in seepage flux and hydraulic head (ground-water level) resulting from ground-water drainage into the first and subsequent cuts of a surface coal mine can be estimated by a technique...
Ground Water Management Using Computers
Both a mainframe and personal computers are used by the Water Use Division of the South Florida Water Management District in the consumptive water use permitting process. Numerical and...
Using Microcomputers for Groundwater Flow Analysis
Micro-computers offer an effective and efficient method for rapid and comprehensive analyses of groundwater flow. There are now numerous codes which have been developed specifically for...
Computer Aided Design of Ground-Water Monitoring Programs
Preliminary evaluation of flow patterns and plume migration by computer simulation aids in determining the spacing of monitoring devices perpendicular to the flow direction, the location...
Portland's New Water Pumping and Hydropower Station
The City of Portland, Oregon, recently placed into service a 100 mgd pumping station as a major milestone in developing a backup and emergency groundwater supply. The facility is also...
Aquifer Management Using Discrete Kernels in Microcomputers
An interactive simulation model based on the 'Discrete Kernel Approach' (a Green's function approach) is presented. The response functions (or the...
The U.S.G.S. Modular Ground-Water Flow Model: Designed to be Understood and Adapted
The paper discusses a carefully designed model program and its complementary complete description of all of the physical and mathematical concepts used in the model. The model program...
Applicability of Groundwater Models to Microcomputers
Microcomputers represent a viable alternative to mainframe and minicomputers for the implementation of groundwater models. The criteria used to evaluate microprocessors are maximum addressable...
Measurement of Hydraulic Conductivity Variation
For a confined, sandy aquifer, the dependence of the horizontal hydraulic conductivity on the vertical coordinate has been measured using single-well tracer injection/recovery experiments....
Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Development and Management Aspects of Irrigation and Drainage Systems
The 1985 Irrigation and Drainage Division Specialty Conference held in San Antonio, Texas on July 17-19, 1985 covered major topics on watershed management and water conveyance, drainage...
Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
Groundwater State of the Art: Is It Adequate?
Representatives from academia, engineering firms, trade associations, and government outline what they believe are the major needs in research, equipment, education and government programs...
San Joaquin Valley Hydrologic-Economic Model
The rapid development of agriculture in the San Joaquin Valley has resulted in increased ground water pumpage. Increasing energy costs coupled with increasing pumping lifts have a major...
Groundwater Basin Storage in Southern California
The feasibility of implementing a groundwater storage program in the Chino Groundwater Basin (Chino Basin) to increase the firm yield of the SWP (California State Water Project) is considered....
Ground Water Economics in the San Joaquin Valley
Ground water pumping in the San Joaquin Valley to supplement surface water supplies has increased from about 200 thousand acre-feet per year at the beginning of this century to nine million...
Drip Irrigated Cotton: Economics and Water Savings
Groundwater withdrawals for cotton production in the arid Southwest account for about 15 percent of all groundwater withdrawals. In Arizona, cotton's proportion of groundwater...
Impacts of an Overboard Disposal Operation
The objective of this study was to establish an acceptable dredge disposal site which would be physically and environmentally suitable for periodic use over the 50-year project life of...
