Flooding risk-points surveillance and risks assessment in Chaeng Sae sub-district, Krasaesin district, Songkhla

Abstract

Focusing on the continuously-repeated flooding in Chaeng Sae sub-district, located on the edge of Songkla Lake as the intense has still impacted imminently. This research aimed to implement community-based participation on both risk-points surveillance and risks assessment of flooding in that sub-district. The surveillance revealed of total 45 flooded risk points with 17 urgent risk points in Chaeng Sae sub-district. More than half of flood problems related to the poor water drainage with blockage of roads or streets, and reshaping the natural waterways into smaller that scattered over communities, agricultural zones and canal system connected to the Songkhla Lake. From the flooding risks assessment, whenever the flood water was in the medium and high level (for disaster level C to E) then it would affect to both agricultural and residential zones in moderate level of 3. However, the mountainous and coastal zones got less impacts.     Better drainage through drainage pipeline’s size in communities and major waterways flow controlling with public collaboration among municipalities, Provincial Administrative Organization (PAO) and Sathing Pra irrigation office. Maintaining the strong local collaboration among the community steering committee with intellectual’s technical supports for developing the practically community-based blueprint of flooding solution.
