“…This basin is separated from the ocean by a constriction across which two bridges have been constructed, potentially increasing dissipative effects. Recent observations within the Wouri estuary (Besack et al, 2020 ;Fossi Fotsi et al, 2023) have indeed shown that tide amplitude is damped in the Douala basin in comparison with the ocean. However the damping remain moderate and is sensitive to both tide amplitude and season (that is to say river flow).The objective of this study is to determine whether WL variations in the Douala basin could lead to flooding in the city of Douala, either presently or in the future.…”
