Optimizing Reservoir Water Management in a Changing Climate
Beça, Pedro; Rodrigues, António C.; Nunes, João Pedro; Diogo, Paulo; Mujtaba, BabarOne of the UN agenda 2030 Sustainable Development goals is associated with water availability and its sustainable management. The present study intends to improve multipurpose reservoir management under climate change scenarios in water scarce regions such as the Mediterranean. Implemented methods include the sequential use of climate model results, hydrological modelling, and reservoir water balance simulation...

Simulated hydropower production under climate change scenarios at Torrão reserv...
Diogo, Paulo; Mujtaba, Babar; Beça, Pedro; Simoes, Sofia; Fortes, Patricia; Amorim, FilipaABSTRACT: Climate conditions have a significant impact on energy demand and production. The project CLIM2POWER, completed in 2021, aimed to develop a climate service at European scale for the planning of the power infrastructures operations using seasonal forecasts and long-term climate projections. This work presents part of the project, and focus on assessing the climate change impacts on hydropower productio...
How sensitive is a carbon-neutral power sector to climate change? The interplay...
Fortes, Patricia; Simoes, Sofia; Amorim, Filipa; Siggini, Gildas; Sessa, Valentina; Saint-Drenan, Yves-Marie; Carvalho, Silvia; Mujtaba, BabarABSTRACT: Climate change will impact renewable resources and electricity demand, usually not jointly considered when designing future decarbonized power systems. This paper assesses how sensitive the Portuguese carbon-neutral power sector is to climate change by 2050 and what are the implications for the formally approved Portuguese Carbon Neutrality Roadmap. The future capacity factors for wind, solar and hydr...

Rock fragments and surface-subsurface hydrological processes at plot and hillsl...
Mujtaba, BabarTese de Doutoramento em Engenharia Civil, Hidráulica, Recursos Hídricos e Ambiente, apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra.; Rainfall-induced surface runoff combined with soil erosion is one of the most important surface hydrological processes and its harmful impact on the environment and communities has been studied for decades. Understanding and modelling surface hydrologi...
The role of stony soils in hillslope and catchment runoff formation
Mujtaba, Babar; Hlaváčiková, Hana; Danko, Michal; Lima, João L. M. P. de; Holko, LadislavThe role of stony soils in runoff response of mountain catchments is rarely studied. We have compared simu-lated response of stony soils with measured catchment runoff for events caused by rains of small and high intensities in the mountain catchment of the Jalovecký Creek, Slovakia. The soil water response was simulated for three sites with stoniness 10–65% using the Hydrus-2D single porosity model. Soil hydra...
Seasonal Forecast Climate Data and Hydropower Production in the Douro Basin, in...
Diogo, Paulo; Beça, Pedro; Simoes, Sofia; Amorim, Filipa; Mujtaba, BabarABSTRACT: The project CLIM2POWER aims at developing a climate service including state-of-the art seasonal climate forecasts in the planning of the operation of the power systems. This work presents part of the project, addressing the forecasting of the hydropower generation in a case study area, the Portuguese part of the transboundary Douro River basin. Rainfall-runoff modelling was performed on a daily scale ...
Laboratory assessment of the influence of rice straw mulch size on soil loss
de Lima, João L. M .P.; Santos, Lara; Mujtaba, Babar; Lima, M. Isabel P. deApplication of crop residues (mulch) over the soil surface is a common practice to control soil erosion and promote infiltration. This laboratory study aimed at investigating the effect of different rice straw mulch sizes on runoff and sediment transport. The experimental runs were conducted using a soil flume of adjustable slope and a rainfall simulator, considering bare soil and three different soil covers: 1...
