Environmental flow, its variability and its impact on aquatic ecology need to be understood in order to assess the impacts of anthropogenic influences on flow regimes and to manage river ecosystems in a sustainable way. In stream and hyporheic zone ecosystems, the effects of hydrological and hydraulic influences on biological processes are usually complex and highly interactive. The aim of this session is to promote a scientific discussion about environmental flow estimation, in order to foster an exchange of different experiences and assessment of approaches. It seeks to evaluate current research knowledge on hydrology, river morphology and other environmental factors and how they affect and are linked with ecosystem functioning across scales.
Contributions are welcomed on the following issues: identification of key flow indicators to be used as environmental flow performance measures, links between flow regime change and related geomorphological and ecological impacts in various aquatic habitats, consideration of spatial and temporal variability of abiotic factors (hydrology, geomorphology, stream temperature) in an ecologically meaningful way, water conservation policies; the impacts of dams, hydropower plants or other anthropogenic regulation schemes on flow regime; sustainability of abstractions and any other issue related to environmental assessment criteria for sustainable water resource and integrated catchment management, including case studies.
