An Integrated Rehabilitation Procedure for Gravity Systems
Demands for an improved system combined with a more adjusted management mode are common in many projects where limited or strained budgets do not allow for a regular and secure water supply....
Crop Yield Models Adapted to Irrigation Scheduling Programs
A crop yield model (CRPSM) was adapted to match the data obtained with typical irrigation scheduling programs. Daily soil water content was calculated from weather data, crop growth stage...
Modeling Branching Irrigation Canal Networks
A mathematical model of branching canal network has been developed based on solving the integrated form of Saint Venant equations which describing steady and unsteady, uniform and non-uniform...
Surge Flow?Automation of Surface Irrigation?At Last
The studies which led to the development of Surge Flow at Utah State University, began as an effort to automate surface irrigation systems. The first prototype models, were electric control...
Irrigation with Reclaimed Wastewater?Recent Trends
Land application of municipal wastewater is a well established practice in California. Much of the reclaimed municipal wastewater (57%) in California is used for irrigation of fodder,...
Furrow Modeling with Variable Hydraulic Characteristics
A zero inertia furrow irrigation model was developed to run on an IBM-compatible micro-computer. The depth gradient term of the momentum equation is approximated by averaging over the...
Modified CIMIS Irrigation Scheduling Program
CIMIS, California Irrigation Management Information System, is a program that collects weather data around the state to assist irrigators in planning and scheduling their irrigations....

This book contains papers presented at the ASCE Irrigation and Drainage Division specialty conference, Irrigation Systems for the 21st Century, held in Portland, Oregon, July, 1987. Environmental...
Planning, Operation, Rehabilitation and Automation of Irrigation Water Delivery Systems
The papers included in this book were presented at the ASCE conference on planning, operation, rehabilitation and automation of irrigation water delivery systems. The conference and this...
Application of Satellite Remote Sensing for Identification of Irrigated Lands in the Newlands Project (
As one element of Operating Criteria and Procedures for the Newlands Project in west-central Nevada, the Bureau of Reclamation has compiled an irrigation water rights spatial data base....
Making Parking Pay
This paper analyzes the financing opportunities and options for providing new downtown parking garages. It identifies the present financial posture of municipal parking agencies, analyzes...
Main Canal Headworks Hydroelectric Project
This project is being installed at the Dry Falls Dam, Coulee City, Washington, adjacent to the Main Canal Headworks which controls the irrigation releases to the Columbia Basin Project....
Impact of Economic Factors on Development of the Lower Euphrates Basin in Turkey
The case of Lower Euphrates in Turkey represents fairly well the dynamic character of multi-purpose projects with respect to technological developments and changes in economic factors....
Reshaping Providence
By moving railroad tracks, river banks and several roadways, Providence, Rhode Island is reclaiming some 45 acres in its downtown and capital districts. This public works package is the...
Agricultural Drainage Policy in the United States Department of Agriculture
Agricultural drainage policies in the United States Department of Agriculture (USDA) generally call for improving the root zone environment for crop production while protecting the resource...
Deferred Drainage?Prudent Policy or Tactical Folly?
The practice of deferring drains has not always worked out as planned. This is particularly true of large outlet drains such as the San Luis Drain in the Central Valley of California and...
The Local Perspective on Agricultural Drainage
This paper discusses shallow, perched groundwater and resulting agricultural drainage and salt problems that have developed in the San Joaquin Valley of California over the past 30 years....
Diamond Fork Hydroelectric Power Development
The Strawberry Valley Project was conceived in the early 1890s as an irrigation project to supply a maximum of 635 cfs of water from the Strawberry Reservoir through a 3. 8-mile-long tunnel...
Modeling an Alluvial Aquifer with Flood Irrigation
Interaction between an unconfined alluvial aquifer, recharged by flood irrigation, and the associated stream system in a glacial outwash area of Wyoming was studied. The United States...
