This thesis which assesses the climate and land use changes impact on flood hazard in Ouémé river basin, Benin (West Africa) focus mainly on (1) trend, break point and non-stationary flood frequency (generalized extreme value distribution) analyses of the annual maximal discharge at the main subbasins of Ouémé basin; (2) exploring potential changes in heavy rainfall magnitude and frequency through the generalized Pareto distribution; and (3) the investigation through multi-modelling approach (WaSiM and SWAT models) how changes in land use (different land use scenarios) would impact on the flood characteristics (frequency and severity).
