Assessment of the Risk of Debris Flows in Zhouqu County, South Gansu Province, China

Abstract:

The hazards of debris flows and the vulnerability to these flows were used as a basis for risk assessment in Zhouqu County, southern Gansu Province, China. The GIS software was used to perform a regional risk assessment for each township in Zhouqu County with a 250 m×250 m spatial resolution. The vulnerability of the population, the economy, and the ecological environment were accounted to develop a comprehensive vulnerability index for each township. A risk assessment model was used to develop a risk zoning map for Zhouqu County. It is found that the areas with the highest risk were mainly distributed in Chengguan, Dongshan, Jiangpan, Dachuan, and Guoye townships. Based on the results of the study, the recommendations for disaster prevention and mitigation were proposed.
