River ecosystems and lake shores are dominated by benthic (bottom-dwelling) communities, including microorganisms and macrozoobenthos. These are bearers of important ecological functions, which until today are only partially known due to difficult study conditions, such as the retention of suspended organic matter and plant nutrients, or the stabilization of the entire food web. The conservation and development of the typical structure, functionality and diversity of these communities represents one of the central objectives of water policy. In the work group the effects of human activities on various ecosystem functions are demonstrated in quantitative ways, and an assessment metric for lake shores according to the EU WFD was developed. Based on this, available ecosystem services for humans are derived, which are further elaborated to form an inter-sectoral decision-making platform, which meets high demand in current water management. In addition, recommendations for the mitigation of the ecological effects of hydropower plants are developed.
