Ground Water Management in the Salt Lake Valley, Salt Lake County, Utah
The perfected and approved water right applications in Salt Lake Valley could potentially withdraw from the principal aquifer a quantity of water far greater than the annual recharge....
Ground Water Management for Wellhead Protection in a Confined to Semiconfined Aquifer, Salt Lake County, Utah
The 1986 Amendments to the Safe Drinking Water Act (SDWA) established the first nation-wide program to protect ground water resources used for public water supplies. The SDWA seeks to...
A Framework for Integrating NPS Pollution Prevention and Optimal Perennial Groundwater Yield Planning
Water management agencies are responsible for protecting and guaranteeing the sustained availability of groundwater of adequate quality. The presented procedure helps determine water Best...
Point Precipitation Models to Simulate Water Balance at a Constructed Wetland
We compare two point precipitation models in a water balance simulation performed at a wetland constructed to treat municipal wastewater. The first precipitation model uses a simple Poisson...
Probabilistic Characteristics of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is analyzed statistically using the hourly rain data at two locations: the flat-plain at Urbana, Illinois and the northwestern Appalachian foothills...
Climate Change: Is Trouble Ahead for Water Engineers?
Very long range forecasts of future global warming from 2 to 5?C have been made as a result of the increase in carbon dioxide and trace gases in the atmosphere due to man's activities....
The Integration and Management of Ground- and Surface-Water Resources for Drought Response in New Castle County, Delaware
This paper reports on a program for the integration and management of ground- and surface-water resources for drought management purposes in the southeastern area of the Commonwealth of...
Controlled Versus Conventional Drainage Effects on Water Quality
Fertilized cropland is a nonpoint source of nitrogen and phosphorus which can contribute to nutrient enrichment problems prevalent in many surface water ecosystems. Research has shown...
Effect of Agricultural Drainage on Water Quality in the Mid-Atlantic States
Agricultural drainage development in the form of drainage alone and controlled drainage-subirrigation (CD-SI) has created conflicts with environmental concerns. Most concerns the lack...
Effect of Agricultural Drainage on Water Quality in the Northeastern U.S. and Canada
Drainage has been used in the northeastern U.S. since colonial times. It has only been since the 1970s subsurface drains have been installed at a significant rate in Quebec. Drainage in...
Models for Simulating Hydrology and Water Quality on Drained Soils
Design and operation of drainage and related water management systems should consider both agricultural production and environmental impacts. This is currently required in many locations...
Effect of Agricultural Drainage on Water Quality in the Southeastern Coastal Plain
This paper is designed to consolidate selected research and results from investigations of the impacts of agricultural drainage on water quality in North Carolina, South Carolina, and...
Effect of Agricultural Drainage on Water Quality in the Humid Portion of the Pacific Northwest
Agricultural drainage first began in Washington around 1830 and in Oregon around 1840. The first efforts to drain soils for agricultural use began by constructing shallow ditches spaced...
Design and Management of Evaporation Ponds
The evaporation ponds in use in the San Joaquin Valley were designed and constructed to dispose of agricultural drainage water in a region of low soil permeability and high water table....
Legal and Regulatory Considerations in Agricultural Drainage Water Management
The institutional and jurisdictional framework applicable to agricultural drainage limits disposal of such flows to evaporation ponds for the foreseeable future. Originally seen as an...
Alternative Drain Water Management Options
Various options are available as alternatives to the shallow, large-sized, earthen evaporation basins that are customarily constructed for disposal of agricultural drainage water in California....
Role of Winter Cover Crops in Reducing Nitrogen Leaching in Sandy Soils
The role of rye as a winter cover crop to reduce nitrate leaching was investigated over a three-year period on a loamy sand soil. a cover crop was planted after corn in the early fall...
Soil Treatment of Food Processing Wastewater
Wastewater from food processing contains a large oxygen demand. Most food processing wastewater requires primary treatment to remove some solids and secondary treatment to oxidize oxygen...
Subterranean Disposal of Irrigation Drainage Waters in Western San Joaquin Valley
Subsurface drainage waters in the western San Joaquin Valley of California are laden with selenium and other toxic elements and above-ground disposal creates a hazard problem (Letey et...
Managing Irrigation in the Presence of Groundwater
A method was developed to use lysimeter data for groundwater contribution to crop water use in the irrigation scheduling procedure for a subsurface drip irrigated field underlain by shallow...
