Abstract

Reliable flood risk level information is significant to take appropriate strategies and measures for flash flood management from area to area in China that suffers heavily from flash flood disasters. A nation-wide project, called Flash Flood Investigation and Assessment (FFIA), was performed during the period of 2013-2016 for the purpose of a great improvement in flash flood management. Based on the data from FFIA on hazard, exposure and vulnerability for each watershed in mountainous area, this study performed flash flood risk assessment by steps of risk index system development, risk assessment model construct, risk component computation and flash flood risk analysis; the risk index system is consisted of three layers of general risk layer, component layer and factor layer (mainly from FFIA); and the model for flash flood risk indicates the overlying effect of hazard, exposure and vulnerability. The main conclusions include: 1) the outcomes of flash flood risk assessment agree well with the places where flash flood events occurred, 2) the protected objects at different risk levels are identified on different administrative jurisdiction levels, and 3) areas with high flash flood risk are highlighted as the Qin-Ba Mountains area, the Wuling-Xuefeng Mountains area, the Wuyi Mountains area, the Nanling Mountains, the Sichuan Basin and its surrounding area, the Yun-Gui plateau, the Yanshan-Taihang Moutains, the Loess Plateau, and the Changbai Mountains; and suggestions were presented for flash flood risk management in these areas according to local conditions of climate, geography, population and urbanization.
