泛区洪水演进的一种简单方法

A Simple Method for Flood Routine on Hood Plains

在利用泛区作为非工程防洪减灾措施中,洪泛区和洼地的洪水演进是一个实际问题,其困难在于泛区内部复杂的边界条件所引起的特殊的洪水波传播形式。本文基于准二维流概念,结合水文水力学方法,提出了一个以相对独立区分块的蓄量演算模型。

Flood routine on flood plain is a practical problem related to the utilization of flood plains and depressions as a non-structural flood control and mitiga-tion measures. The difficulty for solving the problem lies in the particular flood wave propagation caused by complex boundary conditions of flood plains. Based on the concept of quasi-two dimensional flow, a storage routine model, which combines hyd-rological and hydraulic methods and is characterized by considering each relatively independent area as seperate compartment, is presented to tackle the problem proposed.
