| Abstract | This study presents a methodology for flash flood and debris flow hazard mapping in areas with limited hydrological data, focusing on Mae-Sai Market in Chiang Rai Province, Thailand. By integrating GIS inundation analysis, Digital Elevation Model (DEM) data, path distance analysis, and field survey questionnaires, the research develops a hazard map identifying flood potential and direction. The study uses an indicator-based approach for assessing building vulnerability, taking into account factors such as flood frequency, depth, velocity, and potential property damage. The Inundation Hazard Scale (INS) and Flash flood and Debris flow Hazard Scale (FDS) are used to calculate the Flash flood and Debris flow Intensity (FDI), providing valuable insights into flood risk in the area. This methodology offers a practical tool for informing risk reduction and management strategies in regions where hydrological data is scarce or inaccessible. |
