Application of GIS on Flood Risk Area Assessment in Sa Kaeo Province

Likhit Noichaisin

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.     

 

Keywords:  flood risk assessment, Geographic Information System (GIS), Sa Kaeo province
