Flood risk mapping is a high tech approach that offers wide coverage of expected damage by flood events. This paper employed a Geographic information system (GIS) based approach to assess flood influence on the study area based on a 1/50 and 1/100 year flood events. On the basis of social indicators, socioeconomic data were collected to present on spot maps which can be used to pinpoint the vulnerability of people in line with flood-prone area maps presented. This study approach is eclectic in nature, therefore, creating a flood protection standard at the same time the flood susceptibility of populace, building (types), and towns in the region of analysis. The use of GIS as modern technology for flood risk management at the local level is sacrosanct at a time when 2D and 3D model computational efficiency is becoming useful in flood risk decision and policy-making. We recommend further research on flood inundation mapping characteristics and disaster protection standards, this can be complemented by replicating the methodologies presented in this study to enable the advancement of local and global CCA framework.
