Seawater Intrusion in Salinas Valley, California
The rate of intrusion has been estimated to be about 19,000 acre-feet per year. If no action is taken to halt the intrusion, it is projected that in the year 2000 there will be as much...

Subsidence by Rising and Fluctuating Ground Water
Present studies by the U. S. Bureau of Reclamation in California indicate that under certain geologic conditions similar subsidence can also be caused by rising ground-water levels, which...

Agricultural Drainage Policy in the United States Department of Agriculture
Agricultural drainage policies in the United States Department of Agriculture (USDA) generally call for improving the root zone environment for crop production while protecting the resource...

The Local Perspective on Agricultural Drainage
This paper discusses shallow, perched groundwater and resulting agricultural drainage and salt problems that have developed in the San Joaquin Valley of California over the past 30 years....

Expert Systems in Reservoir Management and Planning
Recent advances in artificial intelligence techniques have created a mechanism for incorporating empirical knowledge into algorithmic reservoir planning and management models. The authors'...

Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...

Artificial Recharge for Managing the Great Salt Lake
During the past three years, precipitation amounts throughout the drainage basin have significantly exceeded normal values. The resulting record breaking inflow volumes and lower than...

Recovery of Freshwater Stored in Saline Aquifers in Peninsular Florida
Subsurface freshwater storage has been operationally tested at seven sites in central and south Florida. Injection was into a high chloride water aquifer at six sites, and into a high...

Conjunctive Use and Managed Groundwater Recharge: Engineering and Politics in Arid Lands
In regions with alluvial groundwater basins, increasing consumer demands for water, irregular surface water flows, and high evapotranspiration rates, managed recharge and long-term conjunctive...

America's National Forests: Our Ultimate Water Source
National Forest System lands in the western United States make up 21 percent of the total land area but yield over 55 percent of the region's streamflow and provide more than...

Small Hydro is Very Rarely Typical
Engineering design of a small hydro project is often considered to be straightforward. Many potential developers assume that the engineering effort can be reduced to 'typical'...

Water Management of the Snowy Mountains Scheme Australia
The Snowy Mountains Scheme in south-eastern Australia provides a classic example of Water Resources Planning and Management on a National scale. The Scheme provides mainly peak electricity...

River Basin Network Model for Conjunctive Use of Surface and Groundwater
A generalized river basin computer model called CONSIM is presented for management of the conjunctive use of surface and subsurface storage in an interconnected stream-aquifer system....

Simultaneous Pumping from Layered Ground Water
Laboratory experiments with a Hele-Shaw model and a sand model, and an approximate mathematical analysis using finite elements and the computer, have demonstrated that fresh water can...

Surface Water Analysis for Ground Water Simulation
The California Department of Water Resources (DWR) has applied a hydrologic-economic modeling (HEM) system to the analysis of ground water use in the San Joaquin Valley. An important component...

Design for Comuputer-Aided Water Resource Planning
This paper discusses an integrated approach to computerizing the major functions of regulatory agencies involved in water resource planning and water quality protection. This integrated...

Linking Data Base Management and Computer Models
Storing, tabulating, and graphing large volumes of data, not usually a strong point of a computer model, is more appropriate for a data base management system. A blend of these two technologies,...

Model to Maximize Releases for Supplemental Generation in a Pump-Storage System
An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage...

Intrastate and Interstate Water Transfers
Riparian states generally do not permit transfers of water outside the watershed of origin, while the opposite is true in the appropriation states provided there is no harm to existing...

Evolving Institutions for Water Transfer in the U.S.
A major source of constraint is state water allocation law, which defines rights for water use and development, including in some cases restrictions on place of use that limit transfer....
