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...

Transportation of Cities' Colorado River Water in the Salt River Project's Canal System
Cities in the Phoenix, Arizona, metropolitan area have contracted with the Central Arizona Water Conservation District to take delivery of Colorado River water. Many of their water treatment...

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...

Impact of Farming Systems on Water Quality in Iowa
Increased detection of nitrate and pesticides in surface and ground water has prompted concern about the impact of farming systems on water quality. A number of studies have been incorporated...

Long-Term Effects of Tillage and Crop Rotation on the Leaching of Nitrate and Pesticides to Shallow Groundwater
Contamination of groundwater by nitrate-nitrogen (NO₃-N) and pesticides is a serious problem and concern in Iowa. The extent of contamination can...

Modeling Nitrogen Movement Through Loess Soils
This study evaluates the ability of the Root Zone Water Quality Model (RZWQM) to track the movement and fate of nitrate (NO₃^--N)...

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,...

Nutrient Loads to Delaware's Inland Bays Estuary
A management plan has been developed for the Inland Bays which is a major coastal estuary. Agriculture is the largest contributor of nitrogen and phosphorus to the Inland Bays. Best management...

Phosphorus Transport from Delaware's Rural Watershed
Phosphorus loads were estimated for 62 watersheds. Major land uses in the watersheds were cropland and forestland. Annual phosphorus loads varied from 0.42 to 1.19 kg/ha. Watersheds with...

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...

Imperial Irrigation District Water Conservation
Imperial Irrigation District (IID) and Metropolitan Water District (MWD) have entered into a Water Conservation Agreement to conserve 106, 110 acre-feet (1.31 ? 10⁸...

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...

Enhanced Multi-Dimensional Modelling of Marshes and Wetlands
This paper summarizes the verification and application of a two-dimensional finite element model capable of simulating the complex circulation characteristics in marshes and wetlands for...

Effects of Drainage on Water, Sediment and Biota
The U.S. Department of the Interior started a program in 1985 to identify effects of irrigation-induced trace constituents in water, bottom sediment and biota. The program was developed...

Effects of Wastewater Irrigation on Aqueous Geochemistry
A comprehensive assessment of the environmental impact of a full-scale, operating overland flow (OLF) land treatment system was made of the Campbell Soup, Inc. OLF system in Paris, Texas....

Sensitivity Analysis of a Ground-Water-Flow Model
A sensitivity analysis was performed on 18 hydrological factors affecting steady-state groundwater flow in the Upper Floridan aquifer near Albany, southwestern Georgia. Computations were...

Evaluation of the FASTCHEM Model for Predicting Leachate Attenuation at Fossil Power Plants
The Tennessee Valley Authority (TVA) has applied the model FASTCHEM to identify retardation mechanisms and predict solute transport at two fossil power plants. FASTCHEM (acronym for fly...

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...

Overview and Objectives of the Macrodispersion Experiment
TVA is conducting large-scale field experiments to better define movement and dispersion of contaminants in groundwater. This will support groundwater protection by making possible more...
