BM: basic metavolcanics; LP: lava pyroclastic; ST: sandstone; n.a.: not applicable. The proportion of the land covers was derived from a Landsat image of November 2007 overlaid by the landform map. This was derived by overlaying the landform map with the geology map of Ethiopia. Developed from digital elevation model (DEM). Derived from DEM. Total catchment area is 12.40 km2, and reservoir area is 0.15 km2. Includes closed area, plantations, and natural vegetation. Includes settlements, rock-out crop, and marginalized areas. |
