Abstract: Flooding have been identified by different scholars as a major challenge facing communities, hence this study examines the role of water bodies in the control and management of flood. The study was conducted in Chinda Creek in Ogbogoro section of the New Calabar River, Niger Delta Nigeria. Measurement of study variables was done, this was to identify the influence of velocity, sediment yield, depth and discharge on channel morphology. The channel length measured 643.275m and was divided into 30 sample points were measurement of the study variables were taken. The result from the correlation revealed that channel morphology of Chinda Creek is significantly correlated with discharge and depth. Nevertheless, it has positive correlation with velocity, bed load and suspended sediment load but their correlation were not significant. Multiple regression analysis was used and the result showed that only two variables, discharge and velocity provided 94.8% explanation for the variation in channel morphology. Hence the study recommended planned sand mining of the creek to increase its capacity for discharge as well as serve as a flood control mechanism in the study area.
