The Design of the Surface Fixed Irrigation Canal in the Typical Areas of Sangganhe Irrigation District

永定河上游桑干河灌区是山西省大型自流灌区之一。灌区现有干渠5条,支渠11条,干斗渠74条。计算了典型支渠所属斗﹑农渠设计流量,阐述了灌溉渠道断面的设计思路。

Sangganhe Irrigation District on the upper reaches of Yongdinghe River is one of large-scale artesian irrigation districts in Shanxi province.There are 5 main canals,11 branch canals and 74 main sublateral canals in the irrigation district.This paper calculates the design flow of the sublateral canals of the typical branch canal,and expounds the design thought of the cross-section of the irrigation canal.
