摘要

Disasters caused by flash floods with casualties have occurred frequently in China in recent years. In order to effectively prevent and control them, the government initiated the project of building up a comprehensive nonstructural measure system in 103 pilot counties from 2009. Based on the pilot experience, this project involved 2058 counties of 29 provinces and Xinjiang Production and Construction Corp from 2013. Analysis and evaluation of flash flood disaster is an important element task of this project. According to analyze the characteristics of rainstorm, basic parameters of the small watershed, social economy, the historical flood, etc. in the mountain areas possibly occur flash flood, this task aims to assess the flood control capacity of villages, towns and cities along the mountain rivers, declare the distribution of population and housings in the areas with different hazard grades, estimate the early-warning indexes such as rainfall and water level and their threshold values. The results can support and guide the warning system, forecasting, regional planning, land use and emergency response, and so on for flash flood disaster prevention. This paper will use a case of two small watersheds in Lingbao County of Henan Province to introduce the conceptual framework, methodology, process, key technology, rationality analysis and results of analysis and evaluation on flash flood disaster.
