Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...

Design and Analysis of an Irrigation Pond Using Urban Stormwater Runoff
Stormwater held in detention ponds can be reused for irrigation. A simulation of a mass balance on pond storage volume using rainfall and evaporation data for selected areas is presented...

Education, Research and Training Model for Minority Students in Irrigated Agriculture
Minorities are significantly underrepresented in science and engineering fields in the United States. To attract and retain capable minority students will require the development of programs...

Long Range Planning for System Rehabilitation and Improvement
The Turlock Irrigation District, located in the Central Valley of California, supplies irrigation water to 150,000 acres and electricity to over 60,000 customers. The District's irrigation...

Equitable Distribution of Water in a Rotation Irrigation System
'Volume-based Equity' is proposed as a means of improving the uniformity of water delivery in a rotation irrigation system. Management procedures are developed that can improve water delivery....

A Frost Protection Design for Fruit Trees in Southwest Colorado
The project explores the feasibility of producing commercial quantities of fruit in the high and arid environment of Southwestern Colorado by using low-volume water delivery systems for...

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...

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,...

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...

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...

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...

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...

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...

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...
