IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Assessment of Sedimentation and Flushing Efficiency for Kajbar Hydropower Project in the Nile River
Author : Minh Duc Bui and Peter Rutschmann
The Kajbar dam will be constructed on the Sudanese Nile River for production of electrical energy, water supply and development of agriculture. The dam construction will interrupt the longitudinal continuity of the flow and sediment transport in the river system. Upstream of the dam, most bed load and some parts of the suspended load sediment can be deposited. The rapid reservoir sedimentation decreases the storage capacity. In order to remove and reduce reservoir sedimentation, several technical approaches are developed. Among them, flushing is considered the only economic approach to swiftly restore the storage capacity of the reservoir with severe deposition.In this paper, a method of sediment management and hydro-morphological model for sediment transport and flushing in the reservoir is explained. Due to the scarcity of data for the model calibration, in the present study a reliable quantitative prediction of the morphological evolution cannot be achieved. However, based on experiences formerly gained from model validation and application, a qualitative estimation of bed change under different flow conditions in the reservoir is possible. The calculated results show that flushing can retrieve beneficial storage of the Kajbarreservoir.
