Dynamic Analysis of Multi-Pool Irrigation Canal
This paper discusses the dynamic characteristics of an open multi-pool irrigation canal from robustness point of view. In particular, the presence of right-half plane zeros in an open...

System Downstream Control for On-Demand Irrigation Canals
A nonlinear programming (NLP) Model has been developed to assist downstream control for optimal control of canal systems, called system downstream control (SDC). The objective of system...

Non-point Source Policies for Agricultural Drainage
There is limited experience in regulating the water quality impacts of nonpoint source subsurface agricultural drainage discharges. Recent efforts in California to regulate selenium discharges...

Impact of Agricultural Water Conservation on Water Quality in Arid Irrigated Areas
Water quality constituents of concern in irrigation return flow include sediment, nitrate, pesticides, and trace elements. Each of these components can be affected by irrigation and drain...

Urban Water Conservation Efforts of the Irrigation Association
Water conservation, wise water use, efficient water management: no matter what terminology one uses to describe it, the fact is the topic of using less water permeates the irrigation industry....

Challenges and Opportunities in Egypt's Integrated Water Resources Strategy
Egypt's Nile irrigation system is a very complicated, old operated, continuously expanding system. It may be also described as a highly productive irrigated agriculture system....

Salinity and Hydraulic Issues at a Constructed Wetlands
A constructed wetlands at Boulder City, Nevada was designed to use effluent pumped from the City's wastewater treatment plant. The design was complicated by the highly permeable...

Optimizing Municipal Wastewater Treatment in Cold Climates: Scale, Process and Benefits
Although conventional wisdom demands large, centralized facilities for municipal sewage treatment, much has recently been made of the potential of low tech, decentralized systems for wastewater...

BMP for Control of Agricultural Nonpoint Source Flow
Nine ha of spring wheat were sprinkle irrigated with drainwater from 15 subsurface drains. The objective was to demonstrate that use of drainwater for irrigation improves the net efficiency...

Managing Border Irrigation for Near-Zero Discharge
A dimensionless database of previously executed simulations of sloping-border irrigation with tailwater runoff constitutes the heart of design-aid software showing the effects on runoff...

Climate Variability Impact on the Water Resources of Ancient Andean Civilizations
The great ancient empires of South America used corporate irrigated agriculture with centralized control to help hold far-flung domains together. The Inca empire, larger in area than that...

Multiobjective Optimization of Multireservoir System
In the present study, a detailed multiobjective nonlinear programming model is formulated and applied to a multireservoir system at upper reaches of Krishna river basin in Karnataka State,...

Emerging Concepts for Management of Salinity and Drainage in Irrigated Regions
The purpose of this paper is to very briefly highlight some physical and design concepts important to management of salinity and drainage in irrigated regions in an environmentally sensitive...

Effects of Sewage Effluent Irrigation on Paddy
Paddy, the staple food of South India, occupies about an area of 38 million hectares in India [1, 1987]. Being a semi-aquatic plant, its water requirements are many times more than most...

Canal Control and Automation for the Central District System
The Central Nebraska Public Power and Irrigation District system provides irrigation and hydropower benefits in south-central Nebraska. Because of its complexity, the system relies heavily...

Portable Flumes with Adjustable Throats
Vertically adjustable flumes for canal flow measurements address several problems in field practice. One involves the perception by some canal water users that flumes and weirs always...

Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things?wise water planning...

Eastern San Joaquin County Groundwater Management
An aquifer system of significant volume is located in Eastern San Joaquin County (ESJC), part of California's Central Valley. The industry in that region is primarily agriculture,...

The Management Improvement Program: A Model to Improve the Performance of Irrigated Agriculture
In 1991, the USDA-Agricultural Research Service U. S. Water Conservation Laboratory (USWCL) and a coalition of federal, state, and county agencies initiated a project to develop and test...

Current Status of the Demonstration Management Improvement Program
Coordinated resource management programs have been developed and implemented in the Maricopa-Stanfleld Irrigation and Drainage District (MSIDD) area as a result of the Management Improvement...
