This study evaluates the reliability of ERA5 and ERA5‐Land reanalysis datasets in describing the mean daily air temperature of four climate domains in mainland Portugal. The reanalysis datasets were compared with ground observations from 94 meteorological stations (1980–2021). Overall, the results demonstrated a good degree of correlation between t...

The prediction of river water temperature is of key importance in the field of environmental science. Water temperature datasets for low-order rivers are often in short supply, leaving environmental modelers with the challenge of extracting as much information as possible from existing datasets. Therefore, identifying a suitable modeling solution f...

Water quality modeling can be an important tool for lake management. However, if the simulation period is small and the forcing data is limited, the result uncertainty may diminish its usefulness. This study was conceived with the aim of implementing a long-term water quality simulation of a shallow eutrophic lagoon, with limited forcing data, to e...

The complexity of the state-of-the-art climate models requires high computational resources and imposes rather simplified parameterization of inland waters. The effect of lakes and reservoirs on the local and regional climate is commonly parameterized in regional or global climate modeling as a function of surface water temperature estimated by atm...

WATER QUALITY MODELING AS A SUPPORT FOR CASTELO DO BODE RESERVOIR MASTER PLAN DEVELOPMENT The water quality management process of protected reservoirs located in mainland Portugal is, to a large extent, supported by the implementation of the measures included in the main water management instruments, namely the Hydrographic Region Management Plans...

Hydrological observations in Angola are quite scarce and, as such, the water allocation process, one of the main components of water resources management, is commonly undertaken with a high degree of uncertainty. It is, therefore, vital to increase our understanding of the hydrological processes, namely the frequency distribution of daily streamflo...

O processo de gestão da qualidade da água das albufeiras de águas protegidas localizadas em Portugal continental é, em grande parte, consubstanciado pela implementação das medidas inscritas nos principais instrumentos de gestão do território, nomeadamente os Planos de Gestão de Região Hidrográfica (PGRH) e os Planos de Ordenamento de Albufeiras (PO...

Changes in water temperature and stratification dynamics can have a significant effect on hydrodynamics and water quality in reservoirs. Therefore, to assess future climate impacts, projections of three regional climate models for Europe, under the IPCC A1B emission scenario (2018–2100), were used with the CE-QUAL-W2 water quality model to evaluate...

The Alqueva dam, constructed in the Portuguese section of the Guadiana River, is the centre of a multipurpose project under development in Alentejo, Portugal, which includes strategic water storage, hydropower production, irrigation and urban water supply. Aiming to adequately evaluate nutrient control strategies along the Alqueva watershed in Port...
