- Abstract
In response to the problem of insufficient attention to the risk degree of potential inundation areas in the siting of shelters for dam failure floods, a new model for evaluating the sites of shelters was proposed. On the basis of establishing the risk evaluation index system, the improved catastrophe theory evaluation method was used to evaluate the risk degree and classify the risk level of the potential inundation areas. The distance between shelters and high-risk level areas was taken as the site selection evaluation index, and the disaster risk, location scale, emergency support of shelters were considered. The weights were determined by AHP method, and the TOPSIS method was applied to evaluate the sites of shelters. Finally, 13 potential inundation areas and 10 alternative shelters downstream of Luhun Reservoir in China were used as examples for validation. The results showed that among the areas with high risk levels, Baiyuan Township was a Class I hazardous area, and Pengpo Township, Minggao Township, Chengguan Street, and Longmen Township were Class II hazardous areas. The better evaluated shelters could meet the requirements of paying attention to areas with high risk degree. [ABSTRACT FROM AUTHOR]
