This study aims to locate potential locations for a new evacuation area in Hulu Terengganu, Terengganu, using GIS and the AHP approach. The study was conducted based on the objectives where criteria for flood evacuation area were identified through background research and experts’ opinions. The weights for each of the parameters were calculated using the pair-wise comparison matrix approach by considering opinions from experts in the related field. For this study, five (5) main criteria were considered: namely slope percentage, land use category, accessibility to the shelter, location to the shelter and occupancy, and the scope is limited to physical characteristics. The criteria were then weighted according to importance and those weighted criteria were combined to produce a suitability map. Based on the result obtained, highly suitable area is only 0.05% where it is far from flood prone and hazardous facilities, near to the road network, has suitable land use and also high in population. Next the area for moderate suitable is 4.88% while less suitable with 9.59% of total area in Hulu Terengganu. While most of the area in Hulu Terengganu is not suitable to establish a new evacuation centre, 85.48% of it is because of unsuitable land use, slope percentage and accessibility to the area. © (2024), (Universiti Putra Malaysia Press).
