Book Description
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.

Book Description
Bachelor Thesis from the year 2012 in the subject Politics - Region: Near East, Near Orient, grade: 14,5 p., University of Marburg, language: English, abstract: Since South Sudan's secession in 2011 the Nile River is shared by eleven countries (Egypt, Sudan, South Sudan, Ethiopia, Eritrea, Tanzania, Uganda, Burundi, Rwanda, D.R. Congo, and Kenya) and is home to more than 160 million people. Five of these countries are among the poorest in the world, with low levels of socio-economic development or - in other words - with tremendously high potentials and motivation to socio-economically develop. Today, exploitation of the Nile has reached its limits with ever greater populations and industries depending on its waters. History has created political power structures which represent the exact opposite of the hydrological realites. Although the river receives no contributions from Egyptian territories, the country is the most excessive consumer of Nile waters and dependent on it for about 95% of its freshwater resources. At the same time, precipitation in the Ethiopian highlands delivers some 85% of the Nile's flow measured at Aswan. But the prevailing river regime in combination with a history of political instability has so far prevented Ethiopia and other upstream countries from constructing major schemes to facilitate economic development or even flood protection for its population. Will increasing resource competition lead the states of the Nile Basin to full-scale inter-riparian conflict? Egypt with its very limited availabilty of arable land and already over-exploited and contested water resources must consider to at least partially abandon its pursuit of food self-sufficiency and examine alternative ways of securing its population's needs. Given growing pressures on the Nile's resources, the Basin states' current order will have to fundamentally shift from the current lower-basin domination to a more integrative regional system that appreciates both the upperriparians' contributions and development needs as well as the lower-riparians' dependence upon their cooperation. Considering the most recent trends in scientific literature on transboundary water resources, this transformation is expected to be accomplished through cooperative action rather than resisted against through inter-riparian conflict. This paper argues that Egypt will, despite the repeated threats uttered against underdeveloped upstream states' claims for more equal shares, lose its hitherto dominant position and engage in cooperative efforts exceeding current frameworks like that of the World Bank's NBI.

Book Description
The Nile Basin Initiative (NBI) is a remarkable achievement towards the cooperative management of the common Nile water resources. Based on a Shared Vision Program and a Subsidiary Action Program, the NBI has numerous ongoing projects on the ground. Research on the Nile water resources has been recognized to be crucial for successful implementation of the NBI projects. Therefore, IWMI and other research centers have worked together with the NBI to identify knowledge gaps pertinent to the Nile water resources. This report presents prioritized research questions, pertinent ongoing research projects and the implementing institutions; and available databases on the Nile.

Book Description
This study discusses issues of optimal water management in a complex distribution system. The main elements of the water-management system under consideration are retention reservoirs, among which water transfers are possible, and a network of connections between these reservoirs and water treatment plants (WTPs). System operation optimisation involves determining the proper water transport routes and their flow volumes from the retention reservoirs to the WTPs, and the volumes of possible transfers among the reservoirs, taking into account transport-related delays for inflows, outflows and water transfers in the system. Total system operation costs defined by an assumed quality coefficient should be minimal. An analytical solution of the optimisation task so formulated has been obtained as a result of using Pontryagin’s maximum principle with reference to the quality coefficient assumed. Stable start and end conditions in reservoir state trajectories have been assumed. The researchers have taken into account cases of steady and transient optimisation duration. The solutions obtained have enabled the creation of computer models simulating system operation. In future, an analysis of the results obtained may affect decisions supporting the control of currently existing water-management systems.

Book Description
Through rapid assessment of existing literature and review of policy and other official documents, the report synthesizes the existing knowledge and gaps on policies and institutions and identifies key research issues that need in-depth study. The report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin (BNB) and highlights their relative dependence on, and vulnerability to, water resources and water-related ecosystem services. It also makes an inventory of current water and land related policies and institutions in the BNB, their organizational arrangements, dynamics and linkages and key policy premises. It highlights the major problems in institutional arrangements and policy gaps and makes suggestions for an in-depth Policy and Institutional Studies to be done as part of the Upstream-Downstream Research project.

Book Description
The Grand Ethiopian Renaissance Dam (GERD) will not only be Africa’s largest dam, but it is also essential for future cooperation and development in the Nile River Basin and East African region. This book, after setting out basin-level legal and policy successes and failures of managing and sharing Nile waters, articulates the opportunities and challenges surrounding the GERD through multiple disciplinary lenses. It sets out its possibilities as a basis for a new era of cooperation, its regional and global implications, the benefits of cooperation and coordination in dam filling, and the need for participatory and transparent decision making. By applying law, political science and hydrology to sharing water resources in general and to large-scale dam building, filling and operating in particular, it offers concrete qualitative and quantitative options that are essential to promote cooperation and coordination in utilising and preserving Nile waters. The book incorporates the economic dimension and draws on recent developments including: the signing of a legally binding contract by Egypt, Ethiopia and Sudan to carry out an impact assessment study; the possibility that the GERD might be partially operational very soon, the completion of transmission lines from GERD to Addis Ababa; and the announcement of Sudan to commence construction of transmission lines from GERD to its main cities. The implications of these are assessed and lessons learned for transboundary water cooperation and conflict management.
