In terms of disaster preparedness planning, research on the development of flash flood risk zone maps is essential and many studies have been undertaken globally including Viet Nam. In this study, we propose a method for developing flash flood risk zone maps based on seven components: rainfall, basin slope, river slope, soil (soil erosion risk, forest cover (protective capacity of forest cover), land use (water storage capacity) and specific peak flow. This method is applied to the study area of Thanh Hóa, Nghệ An and Hà Tĩnh provinces, Viet Nam. The produced maps show that high risk areas are distributed along high mountain ranges whereas lower slopes are lower risk areas. © 2020, World Research Association. All rights reserved.
