Managing Urban Growth an Irrigation District's Perspective
Urban growth within the Turlock Irrigation District has converted some property from agricultural to urban use. The District has established policies and developed documents and procedures...
The Potential of Mediation for Resolving Conflicts Between Irrigation and Urban Water Users
This paper discusses the potential of mediation as a means of managing and resolving conflict productivity. Conflict over allocation and use of water may arise from technical or substantive...
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...
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...
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,...
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....
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 Great Lakes and Cornbelt States
The soils and the climate of the Great Lakes and Cornbelt states dictate that drainage is required to carry out economically viable farming activities. When drained, the soils are very...
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...
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...
Watertable Control and Reuse of Drain Water
One of the short term alternatives for disposal of saline groundwater is direct reuse of agricultural subsurface drainage water for irrigation of the land being drained. If the groundwater...
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...
Optimizing Irrigation Management for Pollution Control and Sustainable Crop Yield
We developed a simulation-optimization model which maximizes crop yield while maintaining target salt concentration in the root zone, and/or preventing salt from leaching to the groundwater....
Farmers' Incentives to Reduce Groundwater Nitrates
Nitrate leaching from irrigated crops is a productive input loss to the farmer and a possible source of environmental degradation. This study uses a simulation model to analyze incentives...
A GIS Approach for Studying Irrigation Management Alternatives to Reduce Salt Loading of River Basins
As part of an ongoing effort to improve the water quality of the Colorado River, many methods have been employed to analyze the overall benefits of alternate irrigation management practices...
