    Irrigation canal running status analysis and leakage detection method based on unsteady flow simulation

    • 摘要: 为提高灌区水的利用系数以及实时掌握渠道运行状态,提高灌区管理水平,该文以石头水库东干渠前10 km为研究对象,采用渠道非恒定流模拟方法,对渠道在不同水流情况下的运行状态进行模拟分析,并分析采用该方法进行渠道渗漏检测的可行性。通过模拟分析及渗漏检测验证表明采用非恒定水流模拟方法不仅可以实时了解渠道的运行状态,同时结合渠道水位测量可以进行渠道渗漏点位置检测,从而为提高渠道的安全运行、优化管理提供依据。

       

      Abstract: In order to improve the water use coefficient and understand the irrigation canal running status and to improve irrigation management level, the channel unsteady flow simulation method was used to analyze the water flow change characteristics in several different cases and the feasibility of irrigation canal leakage detection. The front 10 km irrigation canal of the Stone River Reservoir Irrigation District east main canal was taken as study object .The results showed that unsteady flow simulation method can timely understand the irrigation canal running status , and also can detect the leakage position of irrigation canal by combining with the water level measurement, so as to provide references for ensuring the irrigation canal safe operation and optimizing management.
