Abstract

A mathematical model is developed to analyze the flood in 1-D rivers and inundating flow over a 2-D floodplain. The model ia applied to Mekong Delta in Vietnam where the rivers and canals form a network and blocks in the floodplain are surrounded by these rivers. The informations necessary for the application are summarized. Using the results of simulation, the characteristics of inundating flow in Mekong Delta is discussed from the point of view of flood diversion capacity. The result is compared with the actual inundation record in 1994. 1 Introduction A mathematical model expressing overland inundating flow is constituted. The rivers considered here are main Mekong river (Tien Giang), Basak river and several major channels and canals w
