摘要
提出流经配水渠道的平均流量应与各配水口在渠道上的分布及其所控制的面积有关 ,并推导了他们之间的关系。采用簸箕李灌区的实际资料 ,比较了计算结果 ,验证了上述结论的合理性。
Experiential formula =(Q in + Q out )/2 is widely used to determining average flow rate in estimate leakage along canal with uneven distribution of outlets. Average flow rate is correlative with position and service area of each outlets. The Factors affecting mean flow rate were analyzed and validated with an actual irrigation district case.
