Description :
The focus of this paper is to examine the response of the Ntamogba Stream, a very small stream in the heart of Port Harcourt to the increasing urbanization of its watershed and to use findings thereof as guide for similar watershed management. This study highlights that all natural flood receptacles have been destroyed by land speculators and because the catchment's characteristics determine sediment and nutrient inputs to the streams, it was observed that upland disturbance has affected the stream's geomorphic stability.
