摘要
簸箕李灌区的干级渠道作为输配两用渠道,其过流时间较长,流量较大,水量损失亦较大。以干渠传统水量损失测定方法为基础,对这种实践中的算法予以评估并提出新的测算办法。即考虑配水口位置及配水量,用平均流量法和积分法所求得的流量来代替经验公式中的净流量。
Filling the role of both transportation and distribution, the main canal in Bojili Irrigation District has long flow time, high flux and large water loss. Based on the traditional water loss calculation method for main channels and taking the location and water quantity of water distribution into consideration, a new method was established by using the mean discharge method and the integral method to calculate flux for replacing the net flux in the empirical formula.
