A Review of Surface-Groundwater Interaction Models
Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface...
Manning's n From Experiments with Rainfall-Runoff on Portland Cement Concrete Surfaces
Experiments were conducted under artificial rainfall on Portland cement concrete (PCC) surfaces with variable mean texture depths (MTD) and slopes (S). Rain rates were varied up to 3 in/hr...
Global-Scale Assessment of Annual Usable Fresh Water
The quantity of fresh water on earth, although very large, is a limited quantity. A major portion of this water is the polar water that is practically unavailable for human uses. The annually...
Flow Augmentation in the Fenholloway River Basin
Methods to enhance water quality were examined in a north Florida river basin containing industrial wastewater effluent from a paper pulp mill. Streamflow augmentation was determined to...
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...
Management of Supply Canals in a Rotation Irrigation System
Management of the water supply canals in a rotation irrigation system can affect the uniformity of water delivery to farms. Different management procedures are needed, depending on the...
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....
Computerized Maintenance Planning for Agency-Managed Irrigation Systems
Computerized maintenance planning has been established to facilitate: (1) preparation of the 'Catch-Up' Maintenance Plan using the field data collected while conducting the Diagnostic...
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...
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...
