The aim of the research was to solve the problem of economical and efficient consumption of water resources on the water complex under consideration. The efficiency of the irrigation main channels depends on the fact how completely the water reserve supplies in channel pools are used. Control and direct measurement of hydraulic processes characteristics in field conditions are difficult and require the use of mathematical modeling methods and simulation transients studies, which are based on operation algorithms of control tools of hydraulic transient processes in open channels. In the process of research the law of automatic control of water distribution, in which the local hydraulic water levels controls set in the specified pools of the channel, work together on the downstream and upstream pools (with overflowing volumes). 

The results of studies of transition hydraulic processes in the system of Azov main channel pools in order to study the nature of interconnections between the parameters of unsteady flow are given. It has been found that this way of active water distribution management makes it possible to use the existing reserve water in channel pools. This result is achieved by precise control of water level changes at the beginning of the 18th and in the end of the 30th pools. It allows redistributing reserve water supplies along the channel and therefore helps to increase the efficiency of pumping station and water distribution system as a whole. In addition, it is determined that on the 33.5 km long section of a fixed bed of Azov main channel water flow regime is close to a steady one. In this connection, traditional means of measuring the costs and levels are used that will optimize water distribution processes and significantly reduce idle and non-process water discharges from the system.
