Innovative Technology Enhances Water Availability for Irrigation
This paper presents an innovative technology, aquifer storage and recovery (ASR), that is capable of increasing the efficiency of existing irrigation water supply systems. An analysis...
The Role of Irrigation System Management and Performance in Facilitating Water Transfers
Unlike irrigation systems in the U.S.A. that are sustained by farmers in a manner that facilitates urban water transfers, the majority of irrigated lands in developing countries are managed...
Water Resource Management on the Texas High Plains: Controlled Chaos or a Model of Efficiency?
Rarely is a region's social and economic well-being more closely tied to a particular resource than on the semi-arid Texas High Plains, where the water supply is variable, often limited...
Cost Recovery for Multipurpose Water Delivery Systems in Egypt
This study addresses the problem of distributing costs to the beneficiaries of incremental expenditures needed to improve the performance of the Nile water delivery system in Egypt. Emphasis...
Kern County Water Agency?1991 Emergency Ground Water Recovery Program
The 1991 Emergency Ground Water Recovery Program was conceived and implemented by the Kern County Water Agency to deliver water to four water districts to save permanent crops. The Program...
Computerized Irrigation Project Earthwork Design
A procedure was developed to perform earthwork optimization and land-leveling design for irrigation projects using aerial photogrammetry, a microcomputer and civil engineering computer...
GIS Utilization for Analysis of District Drainage Water Recycling
An ARC-INFO GIS system was used to identify physical drainage facilities in a 32,000 ha area of the San Joaquin Valley of California. Once the drainage facilities and linkages were established,...
A GIS Based, Pilot Scale, Wellhead Protection Project for Southern New Mexico
The 1986 amendments to the Safe Drinking Water Act (SDWA) mandated that each state develop a wellhead protection program. Wellhead protection (WHP) means the protection of groundwater...
A GIS Water Planning Model for an Urban and Agricultural Area
Water demand in a region is a mosaic of urban (residential indoor and outdoor, commercial and industrial) and agricultural uses. Yet the typical approach is to aggregate urban water demand...
Strategies to Preserve Endangered Salmon in the Columbia River
The recent listing of some Snake River salmon stocks as threatened and endangered has forcefully brought Pacific Northwest resource interests together to seek solutions to preserve the...
How Federal Mandates to Protect Wetland Resource Value Necessitates a Multi-Agency Approach to Balance that with Other National Economic Goals
A national controversy focused on wetlands exists because of the complex problem of balancing federal mandated protection of wetland values and needs to pursue national economic growth....
USDA Actions to Replace Wildlife Values Lost Due to Irrigation Improvements ? Colorado Salinity Program
USDA is challenged by the conflict generated within the environmental community between advocates wanting irrigation water conservation and water quality improvements and those wanting...
Polyacrylamide Decreases Furrow Erosion
Erosion from furrow irrigated land is a serious problem in southern Idaho and several other areas. Polyacrylamide, a very long chain polymer, increases aggregate stability and flocculates...
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...
Impact of Surge Irrigation on Furrow Water Advance
Surge irrigation was compared to continuous flow in Nebraska from 1983 - 1990. As a result of surge irrigation, advance inflow times were reduced an average of 20 percent compared to continuous...
Some Needs for Irrigation Research in Czechoslovakia
In association with the changes in agrarian and social policy in Czechoslovakia under conditions of economic reform, a transformation of agricultural enterprise has been taking place....
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...
Sustained Yield of the Provo Groundwater Basin
The sustained yield of the Provo Groundwater Basin has been determined by a correlation analysis of the change in groundwater levels with the April-October stream flow at the mouth of...
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...
