The Impact of Soil Erosion in the Upper Blue Nile on Downstream Reservoir Sedimentation

Population growth in the Blue Nile Basin has led to fast land-use changes from forest to agricultural land, which resulted in speeding up the soil erosion processes producing highly negative impacts on the local soil fertility and agricultural productivity. The eroded sediment is transported downstream by water and sinks in the lower basin where...

Sedimentation in reservoirs: Investigating reservoir preservation options and the possibility of implementing Water Injection Dredging in reservoirs

Sedimentation in reservoirs is a consequence of constructing a barrier in a flowing river, which results in a decrease of the transport capacity of the river. The storage capacity of the reservoir decreases due to the accumulation of sediments and the river downstream starts to erode due to the disturbance of the sediment balance. Water...
