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

The Jucar River Basin
J. Albiac,T. Kahil,E. Encarna +2 more
TL;DR: In this article, the authors argue that water markets and institutional policies seem to deal with water scarcity more successfully than water pricing and irrigation subsidies in the Jucar Basin, and they propose a water governance priority to convince farmers of substituting freshwater for the available urban recycled water.

Coulomb stress analysis for several filling and operational scenarios at the Grand Ethiopian Renaissance Dam impoundment.
Austin Madson,Yongwei Sheng +1 more
TL;DR: In this paper, the authors examined Coulomb stress and hydrologic load centroid movements for several Grand Ethiopian Renaissance Dam (GERD) impoundment and operational scenarios, and found that the Coulomb stresses from the highest amplitude season of five long-term operational scenarios are around 36, 33, 29, 41, and 24% of the total maximum stresses.

Exploring the Consistency of Water Scarcity Inferences between Large-Scale Hydrologic and Node-Based Water System Model Representations of the Upper Colorado River Basin
TL;DR: In this paper , the authors compare the performance of two representative models for evaluating the water scarcity vulnerabilities in the Upper Colorado River Basin within the state of Colorado and conclude that the regional-scale model (MOSART) can capture the aggregate effect of all water operations in the basin, but it underestimates the subbasin-scale variability in specific user's vulnerabilities.

Hydrology and Discharge
TL;DR: The climate and hydrology of each of the world's major river drainages are inherently diverse because these drainages cover such large areas that they encompass diverse atmospheric circulation patterns, geology, topography, vegetation, and land use as mentioned in this paper .

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?
Paul C.D. Milly,Julio L. Betancourt,Malin Falkenmark,Robert M. Hirsch,Dennis P. Lettenmaier,Ronald J. Stouffer +5 more
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.

Knowledge systems for sustainable development

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.
