一、小河测流問題的提出結合我国的具体地理与气象条件来看,就可以了解到我国的大多数小河流是属于山溪性的河流。它的特点是洪水由暴雨产生,洪水时期流量大、历时短、水流湍急,有时还帶有大量泥沙、漂浮物等?菟逼谠蛲髁考〉既甑拇蟛糠质逼?水淺流急,或水深流緩。全年的流量变差很大,年最大流 First, the proposed measurement of small river flow Combined with China’s specific geographical and meteorological conditions, we can understand that most of China’s small rivers belong to the stream Creek. It is characterized by floods produced by heavy rains, large floods during the flood, lasted a short time, fast-flowing, and sometimes with a large amount of sediment, floating objects, etc. 菟  Forced 谠   Condyle examination >  both  甑 蟛 糠 bran Forced into shallow water flow, or deep slow flow.
