Abstract PUB provides a scientific means of addressing water related prob­lems in a data-scarce basin like Yewa drainage basin in Nigeria. This study focuses on surface runoff simulation through the generation of geomorpho­logic instantaneous unit hydrographs using digital terrain modelling. The simulation is necessary, in order to provide relevant information needed towards water resources assessment within the basin.
