  Blocking of diversion intakes and canals by sediment deposition is a widespread problem in many spate irrigation (flood water farming) systems. In the Gash Spate Irrigation Scheme (GSIS), particularly the Fota block, sedimentation is a continuous challenge that resulted in 75% reduction of the irrigable land (2012 data). The scheme receives sediment laden flood water from the Gash River which originates from the Eritrea-Ethiopia Plateau. The GSIS is the breadbasket for the Eastern Region of Sudan with over half a million inhabitants. This research focused on sedimentation problem and its remedial measures at Fota diversion intake. The sediment deposition in front of Fota diversion intake reached up to 1.5 m depth. This deposition at the diversion intake plus sedimentation in the canal networks reduces the Fota block irrigable land by 75%. Therefore, providing remedial measures to the .. Read More»
