Abstract

The delineation of flood zones is a recurrent problem for which modelling is very useful to guide preventive decision-making. However, this is a complex problem due to the assessment uncertainty (multiplication of techniques). Here, three flood flows assessment categories are compared: hydrometeorological, empirical and statistical frequency analysis of peak flows. Then, the flood zones were assessed based on the Hec-Ras hydraulic modelling software. The results show higher flood flows in the High Nekor sub-watershed and their increase with return periods still with different flow values for each technique. The hydraulic modelling shows an extended flood area which includes already built constructions. Hence the need to take immediate preventive measures and prepare a flood mitigation and early evacuation management plan.
