磁窑河是山西省晋中盆地的主要排水河道,它担负着汾河和文峪河灌区94万亩土地的退水以及白石南河等14条山洪河道的泄洪任务。由于山洪暴涨暴落,含砂量大,加之河道纵坡较缓,一般多在1:2000～1:4000范围内,河道淤积严重,泄洪能力不能满足要求,常因泄洪不畅,洪水破堤而出,淹没农田;又因

Ciyi River is the main drainage channel of Jinzhong Basin in Shanxi Province. It undertakes the drainage of 940,000 mu of land in Fenhe and Wenyuhe Irrigation Districts and the discharge of 14 flash flood channels such as Shibanan River. Due to skyrocketing floods, large amount of sand, combined with slower longitudinal channels, generally more in the range of 1: 2000 ~ 1: 4000, serious river siltation, flood discharge capacity can not meet the requirements, often due to poor flood discharge, flood breakwater and Out, submerged farmland;
