Land-use changes from natural forest to agricultural land in the Blue Nile Basin has resulted in accelerated soil erosion upstream and sedimentation in reservoirs and irrigation canals downstream. The only effective solution to reduce the sedimentation problems is reducing the sediment input. This book identifies the sources of sediment and quantifies the amounts involved. The methods used in this research consist of extensive field work covering most of the basin, numerical modelling and mineralogical analysis. The results allow identifying the areas providing most of the transported sediment from where it is recommended to start with the erosion control practices.
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 it significantly reduces reservoir storage and irrigation canals capacity. The only effective solution to mitigate the sedimentation problem is to limit the sediment inputs from upstream by locally implementing erosion control practices. However, given the vastness and remoteness of the involved areas, this first requires the knowledge of the most critical zones.
The book identifies the sources of the sediment depositing in the Lower Blue Nile Basin and quantifies the amounts involved providing essential information for the planning and implementation of any interventions aiming at reducing soil erosion. The methods used consist of extensive field work covering most of the basin, watershed, hydrodynamic and morphodynamic modelling and, for the first time, the mineralogical analysis of the sediment at the sources and sinks. The method is successful in indentifying the areas providing most of the transported sediment, where it is recommended to start with erosion control practices.
