近年来,运动波方法在水文界受到普遍重视和较多应用.运动波方法的基础是连续方程和阻力方程,二者都是水力学的基本方程.与水文中常用的推理公式和单位线等方法比较,运动波方法物理概念明确,且方程本身是非线性的,描述洪流演进时就不必再用经验方法作非线性改正.在一般条件下,运动波方程的求解要采用数值方法,而曾使其应用受到限制.随着计算机的发展,这一困难已基本克服.一些著名水文学家认为,水文学将迈出的一步是运动波方法,这种方法已发展成熟,可用于许多水文问题.目前,微型计算机已在我国普及,应用运动波方法具备了条件.本文拟简要介绍运动波方法的原理及应用,供参考.
In recent years, the method of exercise wave has been widely used and widely applied in the hydrology community.The basis of the wave method of motion is based on the continuous equation and the resistance equation, both of which are the basic equations of hydraulics and the common reasoning formulas and unit lines in hydrology Compared with the method, the physical concept of the moving wave method is clear, and the equation itself is nonlinear, so it is not necessary to use empirical methods to describe the nonlinear evolution when describing the evolution of floods.In general conditions, the numerical method is used to solve the motion wave equation, Its application has been limited.With the development of computer, this difficulty has been basically overcome.There are some famous hydrologists believe that hydrology will take one step is the motion wave method, this method has matured, can be used for many hydrological problems. At present, micro-computer has been popularized in our country, and the application of motion wave method has the conditions.This paper intends to briefly introduce the principle and application of motion-wave method for reference.
