摘　　要：渠道过水断面快速准确测定是灌区量水的一项基础性工作,目前,常规渠道水量计量方法主要适用于水体清澈和渠道断面稳定情况。在高泥沙含量的输水渠道中,常规方法测量误差较大。针对上述问题,研发了一种渠道过水断面快速测定新设备,该设备能够真实、有效、快速测定渠道过水断面,能同时动态监测渠道水深和渠底淤积双项指标,适合多泥沙状态渠道过水断面的快速测量。Rapid and accurate determination of the canal section flow is a basic task of flow measurement in irrigation areas. At pres ent, the regular measuring method of canal flow is suitable to the conditions that the water is clear and the canal sections are stable. For the high-silt water-conveying canals, normal measurement has great errors. Aiming at these problems, a new device for rapid de- termination of canal section flow is developed. It can rapidly and accurately measure and determine canal section flow. Meanwhile, it can dynamically monitor the water depth and the bottom sediment thickness of canal. Therefore, It is especially suitable to the rapid measurement of canal section flow when the canal water contains a great deal of sedimentation.
