Current Investigations of Hawaiian Taro Pondfield Irrigation Systems
Due to the prominence of taro pondfield irrigation water in the State of Hawaii's system of water rights, the heightened attention given to water resource management under...
Description and Evaluation of Program: SNUSM
The Staggered Net Unsteady State Model (SNUSM) was developed in the early 1980's by the United States Bureau of Reclamation under the direction of Bob Gooch and Al Graves....
Surface Water/Groundwater Interaction Studies
Studies were performed on a high elevation (2440 meters or 8000 feet) valley stream system and a high (1980 meters or 6500 feet) cold desert stream system in Wyoming, to analyze the surface...
Stream Water Quality Modeling in Ankara Metropolitan Area
At the time this study was undertaken, untreated wastewaters from Ankara metropolitan area (capital of Turkish Republic) were being discharged directly into Ankara Creek and its tributaries....
Underground Water Conservation Districts: A Case Study in Water Resources Management
Ground water supplies approximately half of the annual water use in the state of Texas. The water law system in the state is extremely complex and non-integrated, making the management...
Multicriterion Strategic Planning for Improved Irrigation Delivery Performance
An approach for assessing alternative strategies for improving an irrigation water delivery system in the context of multiple planning criteriais applied to the Alamosa River and La Jara...
Ground Water Impacts from Irrigated Ridge-Tillage
The Northern Cornbelt Sand Plain Project is a cooperative research effort between the State Agricultural Experiment Stations, USDA/Agricultural Research Service and U.S. Geological Survey...
Management, Operation and Maintenance of Irrigation and Drainage Systems (Manual No. 74)
Manual No. 74, Management, Operation and Maintenance of Irrigation and Drainage Systems, is an updated version of an earlier manual published by the American Society of Civil Engineers...
Impact of Nitrogen and Water Management on Ground Water Quality
Nitrate-nitrogen (NO3-N) concentrations in shallow ground water of the Platte River Valley in Central Nebraska have been increasing since the 1950s...
Thermal Regimes at Tailwaters of Hydroelectric Dam
Continuous temperature data were collected in the field for periods of approximately two weeks in Center Hill Tailwater. These data were analyzed to determine the warming rates and travel...
Overview of the Ohio Management Systems Evaluation Area
The Ohio Buried Valley Aquifer Management System Evaluation Area (Ohio MSEA) project is part of a regional study developed to investigate the effects of farming systems on productivity,...
History of Irrigation Water Development in Hawaii
Hawaii has a rich heritage of irrigated agriculture from the time of the first Polynesian settlers to the present. Following the ancient stream diversions by Hawaiians, sugar planters...
Forecasting Irrigation Water Supply Using a Computer Model and Remotely Sensed Snow Cover
Improved streamflow forecasting in the Sevier River Basin is one objective of the Sevier River Water Management Study. Short-term forecasts are needed for optimum operations of irrigation...
Optimization of a Municipal Ground Water Production System in North-Central Oklahoma
A management model is being developed to optimize the municipal groundwater production system which supplies drinking water for the City of Enid, Oklahoma. The system is comprised of one...
Conjunctive Use of Surface Water and Groundwater Management
A mathematical model is presented for conjunctive management of connected surface and groundwater systems. The groundwater module is based on the linear, two-dimensional, horizontal flow...
Monthly Conjunctive Allocation of Water Resources for Eastern Arkansas
The objective is development and use of a conjunctive water resource model as part of a hierarchical approach. In this case, this program is developed to determine the monthly allocation...
Groundwater Management in the Main Aquifer of High Aswaan Dam
The High Aswaan Dam reservoir replenishes a groundwater aquifer which extends on both sides of the dam lake with variable thickness. The groundwater of this aquifer is used to irrigate...
Groundwater Models and Aquifer Restoration: An Overview
In recent years, as the demand for water has increased, groundwater mining has intensified. Data on water use indicate that this trend will continue in the future, and competition is likely...
Risk Assessment and Management of an Oil Contaminated Aquifer: A Case History Study
This paper concerns the provision of the basic information needed for the decision-making process regarding the remedial measures leading to reutilization of an oil contaminated aquifer....
Application of Decision Analysis in Groundwater Remediation Design
The design of groundwater remediation systems involves selecting from a set of design alternatives under conditions of uncertainty. A risk-based decision analysis approach is presented...
