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 Analysis Irrigation systems Canals Automation and robotics Control systems Drainage systems Irrigation Hydraulic properties Water conservation Bibliography Includes bibliographical references and index Notes Print version record Subject Canals -- Automatic control TECHNOLOGY & ENGINEERING -- Hydraulics.
