This paper discusses the question of modeling and simulation of water levels control in open canals as a key decition of water and energy resources scarsity in the vegetation period of agricultural irrigation. The mathematical model of the water levels control in open canals is developed and the outcomes are evaluated using by Matlab’s tool Simulink. In addition, the paper proposes that the pivot weir or overshot gate for water levels control in open canals is simple in terms of precise and quality control of the upstream and downstream water levels control. Then dynamic equation of control object that describes dynamic state of the water levels control was obtained. A functional diagram has been developed and PID control was applied for the water levels control in the open canals. PID control was applied for the water levels control in the open canals to know how faster response the object to disturbance. Based on functional diagram the model of the system was built in Simulink environment and obtained the dynamic response.
