Abstract :
In this study, a model for assessing of flood disaster risk in flood detention basins was developed using a multi-criteria evaluation method of catastrophe theory. An evaluation system of the model was composed of three mesosphere indicators and eleven underlying indicators including disaster-causing factor, socio-economic attributes and biophysical conditions. The model was applied to assessment of flood disaster risk in 61 villages of Dahuangpu detention areas in Tianjin, and risk maps of flood of 50-year return period and 100-year return period were accomplished, which are consistent with the results of previously conducted studies. This model decreases the subjectivity and facilitates the computation of flood disaster risk.
