Globally floods are increasingly among the most devastating natural disasters affecting human life than any other natural disaster. In 2010 alone, 178 million people were affected by floods and the total financial losses in the exceptional years such as 1998 and 2010 exceeded $40 billion, Jha and Jessica (2012). Many parts of Enoch City, the case study, are highly affected due to the flood in 2021 because of the fact that most of the people have built their homes in lower elevations. The main goals of the study are to develop flood hazard maps from which the flood-prone areas exposed to hydrological risk would be identified, give flood warnings, compute water surface profile, map methodology of the flood level areas of different locations in Enoch city, and create management plans for flood control in emergency situations. In order to correctly draw the flood risk maps, the HEC-RAS Hydraulic Engineering Center’s Analysis System is the software that is used for controlling floods, together with the HEC-GeoRAS extension, in ArcGIS. The 10, 50, 100, 250, and 500-year design storms data input into the model and flood hazard maps have been generated. Simulation of floods based on 100 years past flood data has been addressed in the study. The results that have been obtained correlate with the field situation in a very high proportion. According to the simulation, the results specify the number of damaged households for a specific percentage of occurrence floods.
