Pump Plant Control and Automation
Pumping plants for irrigation systems can be separated into two general types: source pumps which provide water to the system and booster pumps which increase the system pressure. Typically,...
Implementation and Management of a High Technology Irrigation System
Eastern Oregon Farming Company (EOFC) irrigates 12,000 acres using a fully pressurized irrigation system. In 1981, the system was operated with minimal flow and pressure measurements and...
Instrumentation: Canal De Provence
A report describing the Canal de Provence and its specific hydraulic regulation system, 'dynamic regulation', is presented in another conference paper. The present...
Instrumentation for Automated Irrigation Systems
Remote site instrumentation sensors are vital components in automated irrigation systems, enabling measurement of water levels, flows and gate positions. It is desirable to select sensors...
Data and Control Communication Methods for Delivery System Operations
The selection of a communication system for the automation of a canal system requires careful consideration of the type of canal system operation desired, the location of the facilities...
Overview of Financial and Economic Considerations
The financial and economic analyses of plans to rehabilitate and automate irrigation water delivery systems are complex technical exercises that require the expertise of professional economists...
Financing Options for the Operation, Rehabilitation, and Automation of Irrigation Water Delivery Systems
The paper discusses potential sources of financing for irrigation improvements and outlines many methods for securing funds. Irrigators who are in need of funds to improve or repair their...
Yakima-Tieton Irrigation District Rehabilitation Program
The Yakima-Tieton Irrigation District obtained funding from the U. S. Bureau of Reclamation and the State of Washington to replace an open canal and lateral irrigation delivery system...
Economic Analysis of Irrigation Rehabilitation Projects
This paper discusses the assessment of the costs and benefits of irrigation rehabilitation and modernization projects. It summarizes the methodology used at the World Bank to assess the...
Air Regulated Siphons as Irrigation Canal Outlets
This paper investigates the possibility of using air regulated siphons as outlets from irrigation canals. Although a solution to a specific problem is sought, it is recognized that the...
Sedimentation of Lakes and Reservoirs in Illinois
A generalized analysis of lake sedimentation rates in Illinois provides a representative 'window' on sedimentation rates of midwestern lakes located in humid...
Controlled-Drainage Supplements Subirrigation in Humid Regions
A computer simulation was conducted using climate and soil conditions of the humid southern U. S. to demonstrate optional operating methods for dual controlled-subdrainage/subirrigation...
Evaluation of Water Quality from a Drainage-Subirrigation System in Georgia
Nitrate-N, Ammonium-N and Phosphate-P concentrations were measured from shallow subsurface wells and outlets of a drainage-subirrigation system in the Georgia flatwoods for comparison...
Choices Between Micro and Mainframe Computers
The explosion of microcomputers (PCs) has shifted a great amount of engineering computing from mainframes to micros. It has also shifted a lot of programming from FORTRAN to BASIC. This...
Models of Border Irrigation for Flat Clayey Soils
Border irrigation is widely used for irrigating pastures in south-east Australia. Inadequate earthworks, design and operation of irrigation layouts have been major causes of waterlogging...
Reducing Maintenance Costs of Irrigation Systems
Reducing the costs of maintaining an irrigation water delivery system is becoming more important as the financial problems of the irrigators become more critical. The maintenance costs...
Sprinkler Erosion Model
The Soil Conservation Service has developed a model to evaluate the effect of various sprinkler irrigation systems with associated agronomic practices. Many researchers have dealt with...
Delivery System Management Via Dynamic Programming
Management of irrigation water delivery systems may involve allocating limited water supplies over both time and space under uncertain future demands. The physical delivery systems are...
Interactive Surface Irrigation Design and Evaluation Software
This paper outlines the features and capabilities of a comprehensive personal computer software system for use by irrigation engineers in design and evaluation of continuous and surge...
A Simulation Procedure for On-Farm Irrigation Systems Planning
