TLDR
In this article, a river basin planning model with a wide range of historical hydrological conditions and increasing coordination between the co-riparian countries was used to analyze the implications of filling the Grand Ethiopian Renaissance Dam and its implications for downstream water resources.Abstract:
Strategies for filling the Grand Ethiopian Renaissance Dam and implications for downstream water resources are analyzed using a river basin planning model with a wide range of historical hydrological conditions and increasing coordination between the co-riparian countries. The analysis finds that risks to water diversions in Sudan can be largely managed through adaptations of Sudanese reservoir operations. The risks to Egyptian users and energy generation can be minimized through combinations of sufficient agreed annual releases from the Grand Ethiopian Renaissance Dam, a drought management policy for the High Aswan Dam, and a basin-wide cooperative agreement that protects the elevation of Lake Nasser.read more

Reply to Comment on ‘Egypt’s water budget deficit and suggested mitigation policies for the Grand Ethiopian Renaissance Dam filling scenarios’ by Kevin Wheeler et al’
TL;DR: In this article , the authors show that the results of the unmitigated scenarios in Heggy et al (2021 Environ. Res. Lett. 16 074022) should match those of the mitigated ones cited in Wheeler et al.

TL;DR: In this article , a planning framework for adaptive management of the Nile infrastructure system, combining climate projections; hydrological, river system and economy-wide simulators; and artificial intelligence multi-objective design and machine learning algorithms, is presented.
Water Resources Optimization using the Nexus Approach
TL;DR: In this paper, the water resources in the Upper Blue Nile River basin were investigated using the Hydronomeas model to produce Pareto optimal solutions of hydropower and irrigation, and a relatively small number of optimized solutions were compared via a social cost-benefit analysis to quantify the net benefit for society and determine the most preferable solution.

Grand Ethiopian Renaissance Dam Reservoir Filling
TL;DR: In this paper, reported and synthetically generated stream flow data were used to estimate required period of time for initial reservoir filling, and it was shown that eight to nine years is likely required to fill the reservoir with 20% of the annual flow of each year held back.

Model Evaluation Guidelines for Systematic Quantification of Accuracy in Watershed Simulations
Daniel N. Moriasi,Jeffrey G. Arnold,M. W. Van Liew,Ronald L. Bingner,R. D. Harmel,Tamie L. Veith +5 more
TL;DR: In this paper, the authors present guidelines for watershed model evaluation based on the review results and project-specific considerations, including single-event simulation, quality and quantity of measured data, model calibration procedure, evaluation time step, and project scope and magnitude.

Stationarity Is Dead: Whither Water Management?

TL;DR: Climate change undermines a basic assumption that historically has facilitated management of water supplies, demands, and risks and threatens to derail efforts to conserve and manage water resources.

TL;DR: This study suggests that efforts to mobilize S&T for sustainability are more likely to be effective when they manage boundaries between knowledge and action in ways that simultaneously enhance the salience, credibility, and legitimacy of the information they produce.

WEAP21 - A Demand-, Priority-, and Preference-Driven Water Planning Model Part 1: Model Characteristics
TL;DR: The WEAP21 model extends the previous WEAP model by introducing the concept of demand priorities and supply preferences, which are used in a linear programming heuristic to solve the water allocation problem as an alternative to multi-criteria weighting or rule-based logic approaches.
