  Watershed Prioritization to Flood Susceptibility Using Geospatial Techniques in a Southwestern Nigeria Basin
  Author(s): Adesola Elizabeth Akindejoye*, O Alabi and T B Adedoja
  
  Drainage morphometric is an essential aspect required for effective control of flooding. Ureje Ogbese River Basin (UORB) has experienced flooding repeatedly for years which has led to the destruction of lives and valuable properties. Thus, it is pivotal to examine the morphometry of UORB and access sub-watersheds susceptibility to flooding. In this work, the 30 m-Digital Elevation Model (DEM) from the Shuttle Radar Topographic Mission SRTM was employed to calculate the morphometrics of the drainage basin. To determine the susceptibility to flooding within the study area, the total ranking technique was adopted to prioritize the sub-watersheds. The results from the morphometric analysis reveal that the UORB watershed is characterized by a dendritic drainage pattern with a total of 5985 streams segment and a drainage area coverage of 2642 km2.
