The aim of this project is to assess the impact of summer low flows on the remobilization of pollutants from river sediments. The analyses are carried out for eastern Austria, where agricultural input and the predicted risk of climate warming on low flow and water temperature are particularly high. The innovative combination of data-based models with laboratory experiments and water quality monitoring allows an overall assessment of the sediment-related risk of quality impairment along the water network. The added value of the derived information is presented for three selected catchments and discussed with stakeholders with regard to water management relevance. From this, recommendations for future climate scenarios will be developed.
