Description :
In this paper, a model for flooded area calculation and damage evaluation is presented. Flooding is divided into two types : source flood and non-source flood. The source-flood area calculation is based on seed spread algorithm. The flood damage evaluation is calculated by overlaying the flooded area range with thematic maps and relating to other social and economic data. This model has been successfully used in the Zhejiang Province Comprehensive Water Management Information System developed by the AA. The applications show that this model is especially useful for most counties of China and other developing countries.
