Transboundary sediment transfer from source to sink using a mineralogical analysis. Case study: Roseires Reservoir, Blue Nile, Sudan

Sediment accumulation hampers optimal water resources management of reservoirs. In the Roseires Reservoir across the Blue Nile River, in Sudan, about 30% of the storage capacity has been lost by sedimentation before dam heightening (2012), despite regular sediment sluicing and flushing. At the same time, increasing soil erosion in the upper...

Quantification of water uses along the Blue Nile River network using a one dimension (1D) hydrodynamic model

In the Nile River Basin, upstream runoff variability is an acute issue to downstream countries, since these countries are almost entirely dependent on Nile waters. Cooperative management of the Nile waters has become urgent, considering climate variations (Conway, 2005; Yates & Strzepek, 1998 a) and the necessity to use the water resource for...
