The research analysed morphological variations of the Woji River between 1986 and 2016 using mathematical extrapolations and temporal data. A 50% reduction in the River mean channel width, full-bank discharge and the stream power was found. Channel siltation occurred due to high sediment fluxes from rapid urban processes versus reduced stream power of the river. Water hyacinth invasion, domestic waste dumps and narrow culvers constricted the river channels. Finally, an impaired river status was found and extinction projected by 2043. Recommended were correction and monitoring exercises to check activities along the river channel and to restore the head stream wetlands.
