Challenges and prospects to reduce sedimentation in small-scale irrigation schemes in the Great Rift Valley Basin, Ethiopia

Excessive sediment deposition threatened the functionality of numerous irrigated agriculture in Ethiopia by decreasing canal capacity, increasing operation and maintenance costs, and impairing the investment in irrigated agriculture. The current research studied sedimentation problems and developed options for sedimentation reduction in two small-scale irrigation schemes in Ethiopia, Arata-Chufa (100 ha) and Ketar (430 ha).
