50年代末,我省水文总站提出的“浙江省综合法单位线”,在水利水电工程设计洪水计算中起到了一定的作用。但是,经过多年来使用,在利用实测的一些大暴雨洪水资料验检时,往往产生峰值偏低,峰现时间偏后的现象。其原因是:流量站、雨量站点分布稀少,资料系列短,测验手段简陋;流域自然地理特征值只能从旧五万分之一陆军地图量算,所量算的集水面积、河流长度、河道坡度等值,和实际有较大出入;所选择的测站从134公里~2的小舜江岩岭站到13560公里~2的瓯江圩仁站,流域面积大小竟相差100倍。所选的65个测站,仅
In the late 1950s, “Zhejiang General Law Unit Line” put forward by Hunan Hydrological Station played a certain role in the calculation of design floods for water conservancy and hydropower projects. However, after years of use, when using some of the actual storm flood data inspection, often have a low peak, the peak appears time after the phenomenon. The reason is: the flow station, rainfall site sparsely distributed, short series of data, simple test means; basin natural geographical eigenvalue can only calculate from the map of the army one hundred thousandth, the calculated catchment area, river length, The slope of the river is equivalent to the actual one. The selected stations vary from Xiaoshunjiang Yanling Station of 134 km ~ 2 to Oujiang Wei Ren Station of 13560 km ~ 2, with a difference of 100 times in area size. Selected 65 stations, only
