is prepared by integration of the drought risk and flood risk maps. The findings revealed that approximately 75,815 hectares, or 25 % of the total land area, exhibited a high multi-hazard risk. However approximately 120,737 and 82,710 hectares, equivalent to 39 % and 27 % of the total land area, respectively were estimated to be experiencing medium and low multi-hazard risk. Further analysis revealed that residential and shrimp farm areas, especially in Nakhon Si Thammarat, Huasai and Pak Phanang Municipality, were under high multi-hazard risk, while agricultural land scattered over the basin exhibits medium multi-hazard risk. Finally, the swamp, located in the southernmost zone of the basin in Cha-uat District, faced low multi-hazard risk
