Automation of water distribution management during the reconstruction of main irrigation canals

Abstract

Abstract Canal automation allows increasing the efficiency of projects for the reconstruction and construction of irrigation systems. Modern technological and technical advances make it possible to regulate the flow of irrigation water at all levels of the system more accurately. The basic requirements for water accounting and water metering systems implemented on irrigation systems are applicable only to the conditions of water distribution static regulation. This is primarily due to the use of water-accounting and water-measuring devices developed and used in conditions of steady-state water flow, when there is an unequivocal relationship between the depth and water flow on the rise and on the decline of levels. Using world experience in connection with new achievements in the field of management theory research, it is necessary to consider how and when to implement automation of water distribution management in the context of reconstruction and construction of irrigation main canals. In addition, practical recommendations on other aspects of channel automation should be taken into account, including the dynamic nature of the system; irrigation infrastructure survey; use of SCADA-systems; improving the concept of water distribution management using automatic control methods.
