【知识点】

从气象上来说，24小时降水量（24-hour precipitation）为50毫米或以上的雨称为“暴雨”（rainstorm/ downpour/ torrential rain）。特大暴雨是一种灾害性天气（disastrous weather），往往造成“洪涝灾害”（flood），在山区还会引发“山体滑坡”（landslide）和“泥石流”（debris flow）。Landslide（山体滑坡）是暴雨使山体不堪重负，由山体薄弱地带断开整体下滑，而debris flow（泥石流）是暴雨使沙土石达到水饱和，在重力的作用下液化的泥沙石向低洼处流动。

山西此轮降水极端异常，导致汾河、沁河、浊漳河等多条河流发生涨水过程及险情。

The dyke of the Fenhe River, a major tributary of the Yellow River, near Qiaodong village in Xinjiang county was breached at about 5 pm Thursday, said the municipal publicity department of Yuncheng.

【知识点】

在水文学上，支流（tributary）指汇入另一条河流（或其他水体）而不直接入海的河流。支流所汇入的河流称为干流或主流（mainstream），两河或多河交汇之处称为合流或合流处（confluence）。与支流相反的情况称为分流（distributary）。

The nearly 20-meter-long dyke breach was closed on Friday.
