Realization of an Early Flood Warning System in the Abobo Commune (Abidjan, C�te D'ivoire): Contributions of HEC-GEORAS and HEC-RAS.

Among the ten communes of Abidjan, Abobo has the sad reputation of being the most vulnerable to the risk of flooding because of its recurrence and the many victims and material damage it causes each year. The demolition of dwellings in the numerous basins is causing more and more households to settle in the Sagbé and Anonkoi Kouté watershed valleys. This makes these populations more vulnerable to floods. This study was initiated to study its drainage system in order to limit the vulnerability of the stakes. The main goal is to prevent the risk of flooding with high performing tools and high precision. For this purpose, data were first collected on the study area. Then a flood simulation model was created. Finally, the future floods of the study area were simulated using the tools HEC-GeoRAS and HEC-RAS. The results of this study made it possible to know the influence of the floods in the valleys of the Sagbé-Anonkoi Kouté watershed, and to make flood maps for the return periods of 5, 25; 50; and 100 years, to facilitate decision-making.
