Abstract
In recent years, disasters caused by flash floods with many casualties have occurred frequently in China. In order to effectively prevent flash flood disasters, the State Council approved the National Flash Flood Control Planning (NFFCP) in 2006. In this planning, non-structural measures are recommended as the first step to be adopted in the prevention of flash floods, debris flow and landslide disasters caused by heavy rainfall. In order to effectively build up a comprehensive non-structural measure system for flash flood disaster prevention, the Ministry of Water Resources has asked the local authorities to conduct studies in 103 pilot counties aiming to explore practical schemes. Based on the experience from these pilot counties, the construction of non-structural measures on flash flood disaster prevention for 1836 counties was officially initiated in 2010. The contents of non-structural measures for flash flood disaster prevention at county level include eight aspects. This paper will systematically illustrate the main contents of this national project for the construction of non-structural measures for flash flood disaster prevention in China. This work could provide a reference for other countries and regions in terms of flash flood prevention.
Highlights
The flash floods referred to occur after heavy local rainfalls, often in mountainous areas
flash flood guidance (FFG) was established by regional River Forecast Centers (RFC) and provided to local WFOs for flash flood forecasting [1]
The pilot projects of flash flood disaster prevention mainly focused on non-structural measures, such as monitoring and warning facilities, warning platforms, evacuation plans, organizational systems, knowledge dissemination, training and exercises
Summary
The flash floods referred to occur after heavy local rainfalls, often in mountainous areas. They are characterized by a quick rise of water levels causing a threat to the lives of those exposed. FFG was established by regional River Forecast Centers (RFC) and provided to local WFOs for flash flood forecasting [1]. After some endeavors in recent years, a set of methodologies on flash flood disaster prevention featuring Chinese characteristics has been established. Construction of non-structural measures on flash flood disaster prevention was carried out in 1836 counties nationwide. This paper first introduces the basic situation of flash flood disasters in China, and focuses on the Chinese government’s efforts to establish non-structural measures regarding flash flood disaster prevention in recent years
