緒言近世按洪水成因分析來推算洪水流量的方法,可分兩种途徑: 1.用流體力學理論:不僅计算繁(?),且因影響逕流的因素太多,不得不加以許多假定和簡化。因之除飛機場和城市排水設計外,很難應用於天然河流。2.根據流域物理特性及暴雨特性(即暴雨在時間上及地區上的分配)對洪水
INTRODUCTION There are two ways to calculate the flood flow in the past: 1. Using the theory of fluid mechanics: not only the multiplication (?) Is calculated, but also many assumptions and simplifications have to be made due to too many factors affecting the runoff. Because of the airport and city drainage design, it is difficult to apply to natural rivers. 2. According to the physical characteristics of the river basin and the characteristics of heavy rain (ie, the distribution of rainstorms in time and area)
