Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...

A GIS Based Synthetic Watershed Sediment Routing Model
For most watersheds, extensive water quality data are not available. Land use, topographic, edaphic and meteorological information is generally available; but without extensive water quality...

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...

Critical Public Issues for Well Head Protection
New Jersey adopted in 1991 a Well Head Protection Program Plan to provide added safeguards to water supply wells. Through extensive public participation efforts the Department of Environmental...

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...
