| 摘 要： | 系统地介绍了一维水动力学(运动波)与水文学方法相结合的数学模型的算法原理。利用已知任意雨型的净雨时程分配,可以随之求出洪水流量过程线。文中将一场洪水计算分为坡面流计算及河槽洪水演算两部分,用57次野外实测洪水进行了验证。结果说明:一个概化的一维模式一旦与水文学方法相结合,可以得到与实测过程线相当接近的成果。模型参数比较稳定;有利于工程的安全和经济;可以电算,也可以手算;便于编程接入各地水情信息自动化系统,服务于防灾、减灾。本篇属论述第二部分。

| Abstract: | The algorithm principles of the math model of simplified one-dimensional kinematic wave combined with hydrology were introduced systematically.The calculation of a flood is divided into two parts: overland flow calculation and streamflood routing.This model can greatly simplify the calculation process,but also retains sufficient practical accuracy.The simulated hydrographs successfully fit the recorded data from 57 measured flood.Parameters of the model are relatively stable.It is easy to compile the model ... |

| Keywords: | kinematic wave combined hydraulics with hydrology nonlinear factor calculated by the measured flood information general model |
