El presente trabajo muestra la aplicación de una metodología para el diagnóstico de un sistema hídrico complejo y extenso, la cual facilita la toma de decisiones robustas de largo plazo en un contexto de elevada incertidumbre tanto climática como no climática. Para ello se modela y se evalúa la ocurrencia de potenciales fallas en el sistema hídrico constituido por las cuencas de los ríos Limay, Neuquén y Negro en la Patagonia Argentina, para múltiples escenarios a lo largo del periodo 2010-2050. Dicha evaluación se realiza utilizando el software WEAP7 y tomando en cuenta diversas incertezas que se presentan hacia el futuro (e.g. el clima, la evolución de la superficie bajo riego y del tipo de cultivos), y posibles alternativas de intervención (e.g. la construcción de centrales hidroeléctricas, la adopción de medidas de eficiencia hídrica en conducción y riego). Los resultados permiten determinar que la construcción de embalses así como la mejora de eficiencia en riego y conducción agrícola (incluyendo la remodelación y / o construcción de infraestructura de riego y drenaje), podrían ser efectivas para mitigar los impactos negativos para la mayor parte de los escenarios climáticos y de superficie bajo riego considerados.

Middle East and North Africa (MENA) regions are increasingly concerned about water scarcity. Egypt, one of the arid MENA nations that relies primarily on Nile water, faces a water scarcity issue because of a mismatch between demand and supply. This study presents an integrated executive system for managing water resources in two regions of Egypt that have traits with many MENA regions facing water scarcities. Hydrological modeling is required for the modeling of water resources, and model calibration procedures should be implemented to compare the simulated values to the observed and measured values to minimize model errors. The Water Evaluation and Planning (WEAP) model was used in this study to simulate the network systems of Egypt’s Minia Governorate on the western bank of the Nile’s narrow valley and Nubariya in the West Nile Delta, the lower reaches of the Nile. Using field data and experience, as well as other inputs, geographic information system (GIS) software digitized streams using satellite-interpreted data. The models were run, calibrated, and validated. The main calibration objective was to reduce the discrepancy between the actual and modeled flows as much as possible. Nash–Sutcliffe efficiency (NSE), percentage BIAS (PBIAS), volumetric efficiency (VE), and agreement index (d) values were calculated for three calibration cases. For anticipating water shortages until 2050, two scenarios were examined: (1) climate change scenarios based on historical climatic data from 1960 to 1990 and from 1991 to 2020, which led to a prediction scenario (2021–2050) of increasing temperature in the areas leading to evapotranspiration (ET) increases of 5.42% and 5.13% and (2) canal lining scenarios, which found a flow saving in the areas, showing that we can overcome the anticipated water shortage progress if canal lengths are rehabilitated by 10% and 25% in Minia and Nubariya.

“…In this research, by considering the quality parameters and using the QUAL2K model and also considering the defined water quality and land use standards, the self-purification potential of this river was evaluated. The BOD, DO, nitrate and total coliform parameters were selected as indicator parameters to evaluate the self-purification capacity of the river [30].…”

Mathematical models are useful for predicting the reactions of watercourses such as rivers due to the entry of contaminants. Some of these models are able to simulate the effects of present and future loadings as well as aid managers and officials in making decisions even if the data are sparse. In other words, river water quality preservation requires more investment in wastewater treatment and/or the installation of collection and control systems; it may also limit activity expansion in the river basin. The conservation of watersheds such as the Maroon and Jarahi basin, which provide water for drinking and for industrial and agricultural use, is socio-economically vital. Therefore, the first stage of managing the conservation of water resources is understanding their qualitative changes. For this purpose, the QUAL2KW mathematical model was utilized to simulate the river water quality in this example region. According to the reported values of water quality parameters and pollutants at monitoring stations, it was established that the river is at a critical condition in terms of biochemical oxygen demand (BOD) pollution due to the discharge of urban and industrial wastewater, as well as high electrical conductivity (EC) due to the drainage of agricultural lands. Based on the statistics calculated during the validation step, the authors concluded that the QUAL2KW water quality model is reliable in the simulation of qualitative parameters and the pollution data of the study area; namely the Maroon and Jarahi river basin located in the south-west of Iran. This will help stakeholders to better manage watersheds with sparse data. This region has been suffering from climate change which has led to droughts and the construction of several dams to retain water. For the second and third stations, the NASH (named after the mathematician John Forbes Nash) values were 0.96 and 0.92, respectively, indicating a relatively high model accuracy. The evaluation using the root mean square errors (RMSE) and NASH showed that the quality of water at the second station was better than the other two stations based on the coefficient of determination R2. Since there were three drains at station number 3, the wastewater entering the Maroon River had a higher level of contamination.
