     Thailand is vulnerable to natural water related disasters, accounting for 25 percent of total deaths among persons aged 60 years old or older. The lack of disaster preparation has further caused unexpected impacts. This study focused on Salaya Sub-district, which is the most vulnerable, and accounted for 60 per cent of all households in Phutthamonthon District. The study is aimed at evaluating flood hazard areas based on the density of senior households in Phutthamonthon District, Nakhon Pathom Province. The use of Geographic Information System with Potential Surface Analysis and overlay techniques for prioritizing the areas based on potential impact and number of senior households in the hazard-prone areas. The results show that most senior households fell into “moderate” flood zones accounting for 47 percent of the total households followed by “high” zones with 27 households (31 percent) approximately.
