Filling the GERD: evaluating hydroclimatic variability and impoundment strategies for Blue Nile riparian countries
TLDR
In this paper, a modelling study is performed to evaluate interannual and decadal-scale streamflow variability into the Grand Ethiopian Renaissance Dam (GERD) reservoir and comparison of various filling strategies for hydropower and downstream releases to Sudan and Egypt from this dam.Abstract:
A modelling study is performed to evaluate interannual and decadal-scale streamflow variability into the Grand Ethiopian Renaissance Dam (GERD) reservoir and comparison of various filling strategies for hydropower and downstream releases to Sudan and Egypt from this dam. To capture these aspects, simulations of probabilistic streamflow via wavelet analysis are produced to define the propensity towards wetter or drier conditions for absolute, threshold and percentage-based filling strategies. Absolute filling strategies have lower uncertainty than percentage-based strategies, benefiting upstream planning; however, downstream releases may be near zero on occasion. Consensus among the riparian countries prior to initiation of filling is strongly encouraged.read more

Understanding and managing new risks on the Nile with the Grand Ethiopian Renaissance Dam.
TL;DR: This analysis illustrates how during filling the HAD reservoir could fall to levels not seen in recent decades, although the risk of water shortage in Egypt is relatively low, and a new normal period after the reservoir fills; and a severe multi-year drought after the filling.

Quantifying and evaluating the impacts of cooperation in transboundary river basins on the Water-Energy-Food nexus: The Blue Nile Basin.
TL;DR: The results show that theEconomic gain of the Blue Nile Basin from WEF increases with raising the cooperation level between Ethiopia and Sudan to collaboration, however, the economic gain of each riparian country does not necessarily follow the same pattern as the economic loss of the basin.

On the representation of water reservoir storage and operations in large-scale hydrological models: implications on model parameterization and climate change impact assessments
TL;DR: In this paper, a computational framework based on the Variable Infiltration Capacity (VIC) model and a multi-objective evolutionary algorithm is proposed to calibrate VIC's parameters.

TL;DR: The method demonstrates how improvements to water security for both downstream riparians can be achieved through dynamic adaptation of the operation of the Grand Ethiopian Renaissance Dam during drought conditions and the robustness of potential management arrangements can be evaluated considering potential effects of climate change.
