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...
Estimating Urban and Suburban Sewage Flows with Assistance of GIS Technology
The Massachusetts Water Resource Authority (MWRA), an agency created by the Massachusetts legislature to provide wholesale water and sewer services to the metropolitan Boston areea, is...
Modeling Variable Width Buffer Zones with a Geographic Information System
It is possible to gain significant protection of water resources from nonpoint pollution with buffer strips, but frequently a single width strip is not appropriate. Geographic information...
Water Planning Using an Expert GIS
The development of an expert geographic information system (expert GIS) for long-term regional water resources planning is discussed. The system is comprised of an expert system to capture...
Lunacy, Legerdemain or Levitation: Legal Assessment of the ASCE Model Water Code
The Water Laws Committee of the ASCE Water Resources Planning and Management Division established a Model State Water Code Task Committee in 1990 which has the task of preparing a text...
Evaluation of the Model Water Code from an Environmental Ethic Perspective
In order to allocate water in an equitable and orderly process, laws have been constructed. The two basic methods of allocation are 1) a market system and 2) a political system. In a market...
What Should the ASCE Model Water Code Committee Do?
The ASCE, Water Planning and Management Division, Water Laws Committee effort to draft a model water code is motivated by the recognition of change and is intended to offer assistance...
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...
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...
Interfacing with the Public on Water-Related Issues?What TVA is Doing
Management of the water resources of the Tennessee River Basin has been a primary responsibility of the Tennessee Valley Authority (TVA) since its creation almost 60 years ago. In the...
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...
Water Supply Operations During Drought
During years when water supply may not be adequate to cover water demands, water supply decision maker or managers need to decide how to spread projected shortages through the anticipated...
Planning and Operation of a Multi-Reservoir Water Distribution System
A water supply distribution system planning model (DSPM) is developed using a directed graph algorithm as its pre- and post-processors and a linear programming (LP) procedure as an `intelligent'...
The 1991 Revolution in Water Management
A revolution in water management took place in California in 1991, the fifth consecutive year of drought. Deliveries from California's major water projects in 1991 were reduced 70 to 100...
