Conceptual Framework for the Risk Assessment of Hydrological Disasters: A Case from Urumqi, China

Abstract

Hydrological disasters have become one of the most serious problems facing regional green development. In order to develop a method suitable for comprehensive assessment of urban hydrological disasters, this paper takes Urumqi, China as the research object, and proposes a conceptual framework. Urumqi is an urban area in the northwest of China, and it is often devastated by hydrological disasters. In combination with urban geographic data and the mathematical calculation model of Urumqi, China, the urban hydrological disasters analysis model of Urumqi is established by using the spatial analysis technology of the Geographic Information System according to the risk index of hydrological disaster. Considering the various related factors, like the hazard risk, vulnerability and exposure of disaster, and disaster environment, the risk assessment framework of hydrological disasters in Urumqi is finally designed. In addition, the framework provides a reference for relevant government agencies to develop disaster prevention and mitigation policies.
