Application of GIS on Flood Risk Area Assessment in Sa Kaeo Province
Abstract
The aim of this study was to assess flood risk area in Sa Kaeo province. The concerned criteria were average annual rainfall (30 years), the distance from surface water, soil drainage, slope, and land use. These criteria were weighted and rated by 10 governmental experts.The results derived from Geographic Information System (GIS) application indicated that the area with low flood risk was 1,685.73 km2, the area with moderate risk was 3959.19 km2, and the high risk was 1,550.52 km2. The measures for prevention and relieving the flood impacts are to improve and extend the rivers or canals for more falling rain storage, to improve drainage system in downtown, and establish flood mitigation and prevention plan for the area with high flood risk.
