Abstract: An automated turnout system is provided for controlling water flow through a turnout gate. The system determines the water flow parameters of the open channel and adjusts the size of the gate opening accordingly. The turnout system includes a flow measurement structure such as weir or flume, a water level sensor for measuring the water level at the flow measurement structure, a flow control gate, an actuator for adjusting the gate and a position sensor for determining the gate setting. A controller determines the proper gate setting based on inputs from the water level sensor and position sensor. The system provides a low cost, practical way to control outflow under varying canal water levels so as to improve irrigation operations.
