Restoration of good-quality and resilient freshwater ecosystems throughout Europe remains challenging despite many actions and measures. Ecological impacts of water quality degradation are complex to characterise in-situ due to multiple issues such as nutrients, sediments, and pollutants, whose transfer is exacerbated by extreme climate events. Understanding their sources and pathways in headwater streams requires in-situ observations along the land-water continuum at various spatial and temporal scales. This session will centre on the effect of the land-water continuum heterogeneity on water quality and its impacts on stream ecology and ecosystem services. In particular, we invite presentations of studies that integrate multiple pollutants and/or highlight the variability of processes across climates and soil gradients linking biophysical and ecological observations in soils and waters. Conceptualization or attention to built-in opportunities of envisaged novel insights from our session for future long-term ecosystem, critical zone or socio-ecological research will of course be well received. Methodological advances for improving multi-scale monitoring of multiple water quality pressures are also welcome.
