The authors studied if the electrical conductivity can serve as a hydrological tracer to capture the intensity and duration of seasonal reverse flow phases in a specific section of River Spree. Moreover, they studied the effect of upstream transport on chemical water quality, i.e. on trace organic contaminant during these reverse flow phases. 

Marine and freshwater researchers using mesocosms synthesise their recommendations on opportunities and limitations for advancing solutions to grand ecological challenges in aquatic ecosystems. They focus on the unexplored potential for using mesocosms to test solutions to human impacts on aquatic ecosystems. This will need novel collaborations between ecologists and technological developers.

The partition dynamics of organic micropollutants between water and suspended particulate matter in riverine ecosystems differs between dry and wet weather. Chemical concentrations and mixture effects in extracts from rivers are dominated by suspended particulate matter during rain, but the dissolved phase dominates during dry weather.
