On Tuesday 26 May, 2020, the PhD Defence and Awarding Ceremony of Ms. Reem Fikri Mohammed Osman Digna, from Sudan, will take place. Professor Pieter van der Zaag and Professor Stefan Uhlenbrook are her promotors and Dr. Y.A. Mohamed her co-promotor.
The title of his thesis is
Optimizing the Operation of a MultipleReservoir System in the Eastern Nile Basin Considering water and Sediment Fluxes
Due to the covid-19 pandemic the defence will be organised fully digital and will not be open to the public.
A video will be made available online after the defence.
The Eastern Nile riparian countries Egypt, Ethiopia and Sudan are currently developing several reservoir projects to contribute to the needs for energy and food production in the region. The Nile Basin, particularly the Eastern Nile Sub-basin, is considered one of a few international river systems with potential conflicts between riparian countries. In the absence of formal mechanisms for collaboration, the transboundary nature of this basin makes sound water resources development challenging. The large seasonal and inter-annual variability of the river flow exacerbates those challenges. A further complication is the high sediment load in the Eastern Nile rivers during the high flow season.
This study contributes to fill relevant knowledge gaps through a better understanding of the methods needed for a complex system of multipurpose reservoirs, considering both water quantity and sediment load. The study quantifies the impacts of water resources development in the Eastern Nile basin and identifies system management options at both regional and country level. Developing a collaborative and unified perspective of the countries towards new projects can be beneficial for all. New operation rules are proposed for improving operation of the current system when new infrastructures are developed and operated either unilaterally or, ideally, cooperatively.
