Statistical Decision Analysis for Interception Wells
In this paper we apply the Bayesian decision analysis to the engineering design of a groundwater interception well whose purpose is to capture a contaminant plume. Two decision variables...
?H and ?4C as Tracers of Ground-Water Recharge
Surface spreading of water from the Santa Clara River is used to recharge aquifers underlying the Oxnard Plain. These aquifers are divided into an upper system about 400 feet thick, and...
Use of the TETrans Model in Predicting ET Effects on Groundwater Quality
Recently Corwin and Waggoner (1991) developed a contaminant transport software package referred to as TETrans, (acronym for Trace Element Transport). TETrans is a useful preliminary assessment...
Ground-water Policy-making Support: USEM Optimization Modeling Plus GIS and Graphics
A support tool for ground-water management decision making involves integration of a multiobjective optimization model, GIS and graphics software. Two results are improved consideration...
Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...
Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...
ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...

This committee report,
Technology?Key to Environmental Success
A three million ton per year coal unloading terminal with 5 km overland conveyor at Jacksonville, Florida, incorporates numerous technical advances to achieve environmentally safe construction...
Soil Contamination Issues at Port Marine Terminals
A preliminary survey of hydrocarbon contaminated soil and groundwater problems in U.S. west coast ports indicates that the problem occurs in most major port areas. Using the Port of Los...
Scheduling of Ground Water Pumpage in Alluvial Aquifers to Minimize the Impact on Surface Water Diversions
The purpose of this paper is to present a methodology to administer the withdrawal of ground water from a basin where stream-aquifer systems are hydraulically connected. The administrative...
Forecasting Instabilities in Groundwater Parameters
A multiprocess Kalman filter recursive procedure is used as a tool for modeling and analysis of noisy groundwater series in order to detect abrupt fluctuations and instabilities in the...
Study of Groundwater Availability in Case of Drought
Groundwater drought events were derived by taking truncation levels through the time series of daily drawdown records from observation wells. Droughts of various truncation levels, namely,...
Groundwater Recovery Program for Southern California
Under its new Groundwater Recovery Program (GRP), The Metropolitan Water District of Southern California will improve regional water supply reliability by providing financial assistance...
Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...
Analytical Prediction of Gasoline Thickness on the Water Table
With the increased use of immiscible fluid products such as gasoline, the threats to groundwater resources by hydrocarbon products are increasing. The success of recovery of the hydrocarbon...
Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...
Alternative Methods of Drainage Management in San Joaquin Valley, California
The subsurface drainage and drainage-related problems in the San Joaquin Valley cost millions of dollars to the State and local economy every year. A number of actions have been proposed...
Indicator Variography for Spatial Characterization of Aquifer Heterogeneities
The qualitative information or soft data from lithologic descriptions is processed using a state-of-the-art geostatistical approach to delineate, with quantified uncertainty, the extent...
