Effects of fine sediment and temperature stress on aquatic communities

Many stream-dwelling species do not only depend on clean water, but also on a functional stream bed. Fine soil particles that are washed out from surrounding fields and settle on the stream bed can result in colmation and oxygen-depletion. By additional "climate-related stress", e.g. higher temperatures and extended dry periods with little discharge, but also by torrential rains that cause additional erosion, these effects can be exacerbated.

In this subproject, the scientists investigate at flow channels and real streams the effects of the expected double burden on aquatic animals. They plan to deduce which measures in the restoration of brooks are most promising for future climate conditions.
