摘要
渠系水利用系数是灌溉水利用系数的重要组成部分,对了解灌区的节水潜力和用水效率具有重要意义。本文通过实地调研分析,在克拉玛依市小拐乡灌区选取了3段干渠以及3段斗渠作为典型渠段,在现场多次分别针对每个典型渠段的高中低3个过流水位,进行了动水法测渗试验,测得了各个典型渠段上下过流断面的流量,掌握了典型渠段渗漏损失情况,分析计算了典型渠段的渠道水利用系数及渠系水利用系数。
The water utilization coefficient of canal system is an important component of irrigation water utilization coefficient,which is of great significance to understand the water saving potential and water use efficiency of irrigation area.Through field investigation and analysis,three main canals and three bucket canals are selected as typical canal sections in Xiaoguai Township Irrigation District of Karamay City.On the spot,the seepage measurement experiments of dynamic water method are carried out for three high,middle and low water levels of each typical canal section,the flow of upstream and downstream cross sections of each typical canal section is measured,the leakage loss of typical canal section is mastered,and the canal section is analyzed and calculated.The utilization coefficient of canal water and the utilization coefficient of canal system water in the section of type I canal.
