The invention relates to a hydraulic model for a sandy channel diversion gate. The upper stream water level and the down stream water level of the gate are obtained through an ultrasonic water level sensor and a temperature sensor. The thickness of deposited sediment of a gate bottom board and the water level are obtained through an ultrasonic sediment level sensor. The opening degree of the gate is obtained through an encoder. A water gauging gate building size structure and the sediment depositing condition are combined, gate water gauging building parameters are corrected, and the gate water passing flow is obtained. By the adoption of the hydraulic model, under the condition that the sand content of a water body is large, automatic gate water gauging with high accuracy can be achieved, and meanwhile theoretical and technological supports are provided for channel dredging and automatic gate opening and closing. 本发明涉及种多沙渠道引水闸门的水工模型，本发明通过超声波水位传感器和温度传感器获取闸门上下游水位，通过超声波泥位传感器获取闸底板淤积泥沙厚度及水位，通过编码器获取闸门开度大小，然后将量水闸门建
