A Morphometric Analysis of Wonji Drainage Basins around Central Rift Valley, Ethiopia, using Geospatial Tools

The morphometric analysis of the Wonji drainage basin of central Ethiopian Rift valley was carried out using geospatial technique. The study was focused to observe the different aspects of drainage morphometry of the Wonji basin. It was observed that the Wonji basin is of mainly dendritic pattern in the upper reaches and trellis pattern in the lower part of the basin. A fifth order rivers drain the basins and morphometric study shows that the basins are characterized by undulating, highly dissected, moderately sloped region with homogeneous geological materials. The study indicates that the area is having poor to moderate ground water potential It also illustrates that geospatial technique is an apt technology for drainage analysis.
