In response to the expansion of oceanborne world commerce, the Ports of Los Angeles and Long Beach, California, in coordination with the Los Angeles District of the U.S. Army Corps of...
Global Climate Change Effects on Water Quality
The annual thermal energy cycle of Shasta Reservoir in California is simulated under scenarios of climate corresponding to present conditions and as predicted by global climate models...
Global Change and Regional Water Resources
Global climatic changes will probably have significant effect on the utilization of regional water resources and will influence markedly the operation of water storage and delivery systems....
Perceptions, Sensitivity, and Solutions; Water Quality 2000
Commencing early in 1971, the Water Pollution Control Federation (WPCF) (now Water Environment Federation) established a series of challenge groups which would develop information essential...
Modeling Instantaneous Residential Demands in Municipal Water Distribution Systems
A modeling scheme is proposed for simulating the intensity, duration, and frequency of instantaneous indoor water use at a single family residence. The intensity and duration of indoor...
Spatial Decision Support System for Toxic Spill Modeling in the Ohio River
Spatial decision support systems (SDSS) are hardware-software systems that incorporate spatial analysis and modeling in a workstation environment. The Ohio River Valley Water Sanitation...
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...
Use of Interactive Simulation Environments for Evaluation of Water Supply Reliability
This paper investigates physical performance measures and their practical application to a regional water resource system for western Washington. Specific criteria for characterizing the...
Demand Management Strategies for Providence Water Supply Board
The Providence water supply is the largest in Rhode Island, and the demands placed upon it continue to increase with the growth of the area as other systems turn to it as a preferred source...
Computer Support for Water Quality Management in San Diego Bay
At present, a variety of computer based systems and techniques, including mathematical models, data bases, information management schemes, statistical analysis packages, and graphical...
Computer-Aided Support for Water Quality Modeling of the Russian River
A computer-aided support system for operation of the QUAL2E-UNCAS modeling packaged has been developed for modeling of the Russian River, California. The system has been created under...
A Decision Support System for Water Quality Modeling
A prototype Decision Support System (DSS) has been developed to evaluate the environmental and economic consequences of alternative farming practices. This system was developed to help...
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...
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...
Engineering Aspects of Wetland Design
Successful wetland enhancement, restoration, or creation projects require integration of desired wetland functions, local hydrologic and soil conditions, and biological requirements into...
Savannah International Airport Environmentally Minded Stormwater Master Planning
The proposed Savannah International Airport expansion required a coordinated effort between engineers and environmental scientists to develop a stormwater management plan which would utilize...
Hydropower, Water Quality and Waste Discharge
Development of multiple hydroelectric projects on large river systems can result in potential reductions in dissolved oxygen (DO) concentrations. Municipalities along the Ohio River basin...
We Need to Integrate Water Transportation and Environmental Protection Planning and Policy
