    Integrated modelling for water quality management in a eutrophic reservoir in south-eastern Portugal

    The Enxoé Reservoir was built in 1998. Since 2000, it has exhibited frequent high chlorophyll-a concentrations, reaching a geometric mean three times higher than the national limit for eutrophication, presenting ...

    Release of Nutrients and Organic Matter from River Floodplain Habitats: Simulating Seasonal Inundation Dynamics

    River floodplains form a complex mosaic of aquatic, semi-aquatic, and terrestrial habitats. While spatially distinct, these habitats are connected through water, carbon and nutrients, and thus ecosystem proces...

    Assessment of temporary streams: the robustness of metric and multimetric indices under different hydrological conditions

    The generalization of ecological results from temporary streams needs the study of those ecosystems across a broad scale of running waters, covering the geographical ecological constraints involved (e.g., prec...

    Assessment methodology for southern siliceous basins in Portugal

    A sampling programme was developed in three stream types, of siliceous geology, from the south of Portugal (small and mid-sized lowland streams and small-sized median altitude streams). The samples were taken ...
