Canal Automation for Irrigation Systems


Book Description

Prepared by the Task Committee on Recent Advances in Canal Automation of the Irrigation Delivery and Drainage Systems Committee of the Irrigation and Drainage Council of the Environmental and Water Resources Institute of ASCE Canal Automation for Irrigation Systems focuses on the technical aspects of modernizing irrigation systems through use of automated canal control systems. Canal automation has always offered an opportunity to save water and improve the efficiency of irrigation water supply projects or irrigation district operations. Recent technological and engineering advances now enable more accurate control of water deliveries throughout all parts of an irrigation project. Using information collected from irrigation systems around the world in conjunction with new advances in control theory research, this Manual of Practice examines how and when to implement canal automation within the context of canal modernization. Topics include: the modernization process, constraints, and concepts; survey of irrigation physical infrastructure; SCADA systems; control operation concepts; canal hydraulic properties; control methods; verification of controller performance; and implementation of control systems. MOP 131 is an essential reference for professionals in agricultural and irrigation engineering, as well as owners, managers, and operators of irrigation water delivery systems.







Water and the Environment


Book Description

"Water and the Environment" addresses imbalances between availability and demand, degradation of surface and ground waters, inter-sectorial, inter-regional and international competition in water management.




Feedback and Control for Everyone


Book Description

This intriguing and motivating book presents the basic ideas and understanding of control, signals and systems for readers interested in engineering and science. Through a series of examples, the book explores both the theory and the practice of control.




Irrigation Return Flow Water Quality as Affected by Irrigation Water Management in the Grand Valley of Colorado


Book Description

This study was designed to meet the specific needs of the Environmental Protection Agency consistent with the interests and research goals of the ARS. The specific objectives of the study are: (1) to identify variables needed to predict effects of deep percolation, tailwater runoff, and lateral seepage on the quality of return flows. Includes evaluation of quantity and quality of various components of field water balance. (2) To define the effect of irrigation water management on the quality of runoff and deep percolation leaving the farm unit, and determine the reduction in both water and salt losses achievable through improved irrigation technology. (3) To identify mechanisms by which the salt load of return flow water is modified after it leaves the farm unit and moves toward the Colorado River; to attempt to determine the most practicable control methods for salt accretion. (4) To evaluate the experimental methods used in the above studies with regard to their applicability in other similar irrigated river valleys.
