Abstract

The occurrence of natural phenomena such as floods has caused serious consequences for human societies The simulation of flood hazard maps and its depth in a river is one of the most complex processes in hydrology In fact both geomorphological and hydraulic procedures for deriving the flood hazard maps and depth are imperfect at watershed scale In this study a combination of both procedures using a probabilistic approach is used Flood inundation maps for 2 10 2550 and 100return period floods using flood routine within HECRAS in combination of ArcGIS and topographic wetness index TWI map were produced TWI threshold was identified using a maximum likelihood method in order to produce flood prone areas and calibrated over the reach of Zirab City The correlation between TWI threshold and the flood depth was carried out and simple linear regression developed for various return periods The resulting regression model is used in order to create flood hazard maps with various return periods at watershed scale
