Floods are a major problem affecting many parts of the world. Generally, the Cuvelai Etosha Basin (CEB) of north-central Namibia and specifically Oshakati and Ongwediva towns are no exceptions to this problem. Flood analysis in Oshakati and Ongwediva was carried out to map and determine drainage patterns, inundated zones and flood susceptibility. Results of data analysis has indicated that Oshakati town is prone to flooding than Ongwediva town. This is evident from very high and high flood susceptibility classes that occupies a large area in Oshakati town than in Ongwediva town. Moreover, Oshakati town has more of its land falling within shallow depressions, streams and inundation in comparison to Ongwediva town.
