ABSTRACT

The Kulfo River, flowing in the ‘Main Ethiopian Rift Valley’, is one of the important rivers of SNNPR. The river profile, volume of river water flow, rainfall, topography, geology, climate and land use are the controlling agents for the erosion, transportation and deposition of sediments in this area. A total of seven sediment samples collected at water-land interface along the Kulfo River have been utilized for their granulometric analysis. The study reveals unimodal, moderately to well sorted fine sands in upstream indicating a single source of sediment supply in the river. Farther away from upstream, the textural properties of sediments indicate bimodal to polymodal, poorly to moderately as well as well sorted medium to fine sands reflecting more than one source of sediment supply
