Flood has become an annual event in an area of east coast area of Peninsular Malaysia due to heavy rainfall during monsoon season. Although it happens every year, the effects caused by flood cannot be reduced and it remains an inordinate threat to people since the flood hazard map methods apply is not comprehensive . Therefore, effective flood hazard map management process is needed in order to overcome and reduce the losses in the future. The flood phenomenon occur will leads to a tremendous effects in terms of social, economic and environmental degradation. Recently in the year 2014, Kelantan again experienced massive flood that almost the same as the previous record in 1967 in terms of scale and intensity. Thefore the study area is located at Kuala Balah, Jeli, Kelantan. The total area of the study are is 25 km² and bounded within the coordinate of 5° 28’ 0” N, 101° 54’ 0” E and 5° 25’ 30.0” N, 101° 56’ 20” E . The objectives of this study area to update the geological map of the Kuala Balah, Jeli, Kelantan with scale of 1:25 000 , and to produced flood hazard map by identifying the flood zones of study area .Geological mapping that were carried out to identify geological features that have in the study area . Futhermore this geological map of Kuala Balah, Jeli, Kelantan has been updated. Then for the flood hazard map ,the methodology used in conducting this study includes data collection which encompasses of the information from site mapping, interview and questionnaire and also the data obtained from the government department and then analyze by using AHP. The data is further proceed with digitizing and integration which are then analyzed to generate the map. The result show that the flood hazard area was categorized into three levels which are low, medium and high to differentiate the degree of risk at that area. Therefore , this study is very useful to the Kuala Balah villagers , in order to improve flood mitigation process and flood management for future plan.
