STUDY ON PROPOSING AN INDICATOR SET FOR ASSESSING RISK LEVEL OF FLASH FLOOD IN VIET NAM MOUNTAINOUS RIVER BASIN

Abstract

Flash floods in the mountainous watersheds have been causing serious damages to people, property and habitats. Therefore, studies on the risk assessment of flash floods in mountain river basin have become very necessary, in which the development and establishment of a set of indicators to assess the vulnerability of flash floods is of high importance and may serve as the basis for calculating and establishing risk maps for flash floods and proposing solutions response compatibility. Indicator set for assessing the risks of floods for the river basin mountains are built on the basis of local and international researchs, combined with experts’ consultation to create the indicator set with high reliability and applicability. This study aims to develop and establish an indicator set to assess the risks posed by flash floods in mountainous watersheds. In this article, 6 hazardous components indicators (H); 4 level indicator components exposed to hazards (E) and 68 component indicators calculated vulnerable due to flash floods (V) on mountain watersheds have been developed.
