前言天然流域暴雨洪水非线性问题是一个十分复杂的自然现象,它不仅受下垫面坡面沟槽滩等汇流特性的影响,而且受上垫面暴雨的时空分布和暴雨中心运动的影响。现行各类研究方法中,对非线性汇流参数的确定一般均采用经验关系法,其精度常受资料局限性的制约。本文重点研究汇流非线性指数的水力学基础,蓝提出现行非线性指数的成果表。此外对暴雨中
Preface Non-linearity of storm flood in natural watershed is a very complex natural phenomenon. It is affected not only by the confluence characteristics such as trench beach on the underlying surface but also by the spatiotemporal distribution of rainstorms on the underlying surface and the center of torrential rain. In all kinds of current research methods, the empirical correlation method is generally used to determine the nonlinear convergence parameters, whose accuracy is often limited by the limitations of the data. This paper focuses on the hydraulic basis of convergence nonlinear index, blue presents the results table of the current nonlinear index. In addition to the heavy rain
