Floods are recurrently appearing in the headings of local, national and international mass media. Flood as a geo-hazard challenge in many populated territory on the planet. People are trying to mitigate and find ways to minimize damages. Among the initiatives are flood mitigation plans. These tactics can be classify into two categorihich is (a) structural flood mitigation is where physical structures are constructed or modified to reduce the impact of flooding on individual properties or whole catchments, and (b) nonstructural flood mitigation can be considered as a lot of moderation as well as adjustment estimates that don�t utilize customary basic flood safeguard measures. The tricky situation in handling flood challenges is the multilayered information that need to be deciphered by the hydrologists in the decision making. To deal with the flood occasions requires to a noteworthy degree a decent plan and development of a flood control system, and taking appropriate measures for flood relief including non-basic measures, flood determining, cautioning and moderation plans. This paper looks at the evacuation route selection through multi-criteria decision-making. The Analytical Hierarchy Process (AHP) technique is utilized to choose the best evacuation route over variance weighting of different criteria and subcriteria. A learning-driven expert-based GIS model for Kelantan river basin was developed with three design parameters, i.e. accessibility, technical and safety. The model successfully predicted the best route for evacuation centres in Kelantan. In common, the developed model were reasonably accurate. The resultant maps would be useful for regional flood mitigation planning. � 2020 Alpha Publishers. All rights reserved.
