Transferable Rations for Drought Management?
This paper examines the concept of transferable water rations from an economic perspective. Transferable water rations may improve efficiency in the distribution of water by allowing customers...

Analysis of Groundwater Quality: A Database Application for the Nassau County, NY, Water Management Plan
Nassau County, Long Island, New York is presently developing a Comprehensive Water Management Plan. To determine the extent and trends in nitrate contamination of the groundwater, a preliminary...

Numerical Model Study of Groundwater Movement in an Aquifer of Bangladesh
Annual groundwater level variation in the aquifer of the Mymensingh-Tangail area of Bangladesh was simulated by applying an implicit finite-difference model of groundwater flow. The groundwater...

Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...

Oil Spill Impacts on Aquifers
This study attempts to evaluate the seismic hazards along a forty inch pipeline and the impact of a pipeline rupture in the recharge area of the aquifer serving most of West Tennessee....

Application of a Water Budget for Instream Flows
A portion of a water supply reservoir can be dedicated to supplying instream flows. This subreservoir is operated to provide instream fish habitat below the reservoir when releases to...

The Use of the IWR-Main System as a Planning Tool in Phoenix, Arizona
The IWR-MAIN water demand forecasting model is used extensively as a long-range planning tool by the Phoenix Water and Wastewater Department. Its specific applications include: conservation...

Vaporizing VOCs
The authors summarize the findings of a study for the Environmental Protection Agency on vapor extraction of volatile organic compounds from soils. The potential for ground water contamination...

Managing Water-Related Conflicts
the Engineer's Role
The problems facing water resources planners and managers are extensive. The major challenge is finding the key to cooperative rather than divisive approaches to water resources management....

Boundary Fitted Estuarine Water Quality Model
A two-dimensional, vertically-averaged boundary fitted coordinate pollutant transport model was developed for application to estuarine and coastal sea regions. The governing convective-diffusion...

Three-Dimensional Modeling of Pollutant Transport
A numerical model for pollutant transport in coastal waters has been developed in x-y-z-t space. The simplicity of a fixed Eulerian mesh and a computationally efficient Lagrangian approach...

Water Resources: How Do We Slice the Pie?
New and better ways must be found to: reduce water consumption; preserve environmental values; conserve and protect existing water supplies; use surface and ground water conjunctively;...

Glacial Icemelt in the Wind River Range, Wyoming
The Wind River Range of Wyoming contains the greatest concentration of glaciers in the American Rocky Mountains with two of the larger glaciers being Dinwoody and Gannett Glaciers. This...

Possible Climate Change and Its Impact on Snowmelt and Water Supply in California
Global climate modelers are forecasting relatively large future climate change, with warming of 2 to 5?C. These changes, if they do occur, would have major impacts on California's...

Procedures Used for Determining Water Rights on the Caribbean National Forest
In response to increasing demand, the Commonwealth of Puerto Rico enacted legislation requiring current users of water to file existing water uses. Application for water rights on the...

Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...

Water Use by Naturally Occurring Vegetation
A new publication is available to aid the practicing hydrologist or engineer in estimating the water use of naturally occurring plants. It serves as a general introduction to the subject...

Evaluating Spring Flow Trends at Pipe Spring National Monument and Vicinity, Arizona
A study conducted by the National Park Service Water Resources Division is resolving if ground water pumping is causing spring flow declines at Pipe Spring National Monument (PISP). Ground...

Upgrading of the Orange Cove Irrigation District Water Distribution System
The Orange Cove Irrigation District covers about 28,000 Acres in the Central Valley of California. It is supplied from the Friant-Kern Canal. A semi-closed low pressure pipeline system...

Conjunctive Use of Surface and Groundwater
A computer model was developed by T. Sammis and Z. Samani to simulate the conjunctive use of surface and groundwater. The model consisted of a groundwater simulation subroutine and a crop...
