Part of: Planning, Operation, Rehabilitation and Automation of Irrigation Water Delivery Systems


The distributed control system for water delivery that has evolved in Alberta, Canada is described including the type of hardware used and the general operating philosophy. Of importance is the operator interface. The dropleaf overshot gate is presented as hydraulically more suitable and intuitively easier for the operator to adjust (both manually and automatically) as compared to the radial gate for water level control applications. An important component in securing operator acceptance of automation has been to involve operators in the conceptualization of what the system should do and how they should interface with it. One useful strategy is the use of a voice synthesizing communications controller that is capable of reporting site conditions upon demand, or upon alarm. These and other aspects of the subject are discussed.
