A Simple Method for Flood Routine on Hood Plains

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 mitigation 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.
