Description of the Application of Goal Programming for Selective Withdrawal Structure Operation
Thermal stratification in reservoirs results in variations of water quality with depth. Selective withdrawal structures with outlets at different vertical locations, can be used to provide...

Conservation Measures in Urban Storm Water Management
The management of storm water runoff has been given considerable attention by regulatory agencies and practicing engineers in recent years. The current state of-the-art of storm water...

Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...

Simulating Water Supply Systems of the Raritan Basin
A recently developed interactive river-aquifer system model (IRAS) was used to study the Raritan River Basin as part of the effort to revise the New Jersey Statewide Water Supply Master...

Nakajima Subsurface Dam
A new water resource is generated by a subsurface dam. This paper presents the design, construction, and monitoring of a test subsurface dam in an alluvial valley of an island for both...

Designing Under Uncertainty When We Can Reduce Uncertainty: When is Another Observation Worth the Cost?
A method is presented that optimizes the selection of sites for observation of an uncertain parameter when that parameter is used in the risk-based design of an engineered system. The...

Balancing Water Allocation and Water Quality: The Model State Water Code
The Model State Water Code (hereafter called the 'Code') currently being developed by an ASCE task committee is intended to provide a source of legal norms of water allocation for use...

Water Policy and Management: Solving the Problems in Southern New Jersey
Southern New Jersey, which has relied solely on groundwater to satisfy its water supply needs, is depleting the primary source for that water. Symptoms of this depletion include declining...

Water Policy Change, Implications for Pyramid Lake
Pyramid Lake is part of and is surrounded by the Pyramid Lake Indian Reservation. The river system has been administered by a Federal water master serving the Federal court system with...

Understanding the Uses of History in Water Resources Planning and Management
Understanding how water resources decisions (technical, regulatory, structural, or managerial) have been made is necessary to provide the water industry with a perception of complex human...

Joint Optimization of Groundwater Remediation and Monitoring
We describe the challenge of devising optimization methods which optimize jointly the remediation and monitoring at a contaminated site. We refer to the dual control method as a promising...

Water and Wildlife Enhancement with Land Retirement
This case analysis compares costs of land retirement and current on-going structural improvements for salinity reduction in the Colorado River. Results suggest land retirement programs...

Decision Support System for Conjunctive Use Under Complex Water Right Conditions
A prototype microcomputer based decision support system (DSS) is presented for assisting in the conjunctive use management of surface and groundwater under the water rights doctrine of...

Aquifer Storage and Recovery at the Centennial Water and Sanitation District
water in a suitable aquifer, the peak time capacity of CWSD could be increased while delaying the water treatment plant (WTP) expansion currently scheduled for 1996. To validate this assumption,...

Evaluation of the Water Supply Potential of the Floridian Aquifer in Seminole County, Florida
In Seminole County, Florida, a occurred in the 1980s and early 1990s due to a large influx of residents. This large increase in demand, when coupled with a limited groundwater supply,...

Denver's Direct Potable Water Reuse Demonstration Project
The Denver Potable Water Reuse Demonstration Project was created to provide definitive answers to the interrelated questions of product quality, public health, technical and economic feasibility,...

Potable Water Reclamation?A Practical Option to Traditional Sources
This paper describes the development of potable water reclamation alternatives to meet the future municipal water needs of the City of Colorado Springs, Colorado. By the year 2042, the...

Water Polishing by Constructed Wetland Ecosystems
This paper gives results of a five-year study of minerals and nutrients reduction in a large constructed wetland facility in Central Florida, on the periphery of Orlando. The 120 ha system...

Dam Safety Issues Related to Urban Detention Ponds
Detention ponds located within or adjacent to individual residential developments provide significant benefits by improving water quality and preventing damages from floods up to the design...

Channel Stabilization and Retrofit
In 1990 King County Surface Water Management Division completed the Soos Creek Basin Plan. This basin was one of the most rapidly developing areas in the State of Washington. The goal...
