Reactive Irrigation Scheduling for Sloping Furrow Irrigation
We developed a technique for estimating the proportion of the applied irrigation water that is effective when using furrow irrigation. To apply the method, irrigators would need to know...
Optimal Contaminant Plume Management with US/WELLS
A micro-computer based software package developed at Utah State University for computing optimal pumping strategies for well systems (US/WELLS) is demonstrated. US/WELLS is used to determine...
Modeling the Distinction Between Regional Flow and Flow to Drains
Previous research at the Newlands Agricultural Research Center, in Fallon, Nevada, suggests that the quality of the water flowing to the 15 subsurface drain laterals in related to the...
Optimizing Conjunctive Water Use in a Dynamic Stream-Aquifer System with US/REMAX
Long-term water management planning models frequently use large time steps and must employ fairly crude assumptions (such as average climatic conditions, etc.). Managing stream aquifer...
Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
Water Distribution Plan Utah Lake/Jordan River Basin
The Utah Lake/Jordan River basin is comprised of several river systems that are hydrologically related but, for the most part, have been managed and operated separately. To further complicate...
Computer Modeling Approach to Optimize Pumping for Containment of LNAPL Contamination in Unconfined Aquifers
This paper presents an approach to optimize pumping for immobilizing a floating contaminant consisting of a light non-aqueous phase liquid in an unconfined aquifer. The approach combines...
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...
Estimating Runoff from Precipitation and Temperature
Increasing demands for water and the global climate change resulting from the CO2 buildup in the atmosphere require an improved evaluation of surface-water...
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...
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...
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....
