In search for the ecological and toxicological relevance of sediment re-mobilisation and transport during flood events.

摘要: In response to increasing concerns about the potential toxicological impacts of (extreme) flood events, scientists from several disciplines have joined form interdisciplinary research project named FLOODSEARCH. FLOODSEARCH is one recent Pathfinder Projects supported by German Excellence Initiative via Exploratory Research Space at RWTH Aachen (ERS). aims combine methodologies hydraulic engineering and ecotoxicology in a new approach assess risks associated with re-mobilisation particulate bound contaminants often observed after severe events. Impacts extreme events aspects sediment-bound toxic compounds will be characterised evaluated controlled experiments fusing simulation technologies biological effects assessment. The overall goal establish novel more realistic towards event testing that can applied number different questions species. Specifically, model aquatic species such as rainbow trout (Onchorhynchus mykiss) exposed particle-bound flood-like conditions specifically designed annular flume permits monitoring both physical/chemical parameter. Ultimately, this assist further our understanding increasingly frequent e.g., consequence climate change, bridging gap between physical (re-)mobilisation resulting on organisms. Thus, it objective derive relationships hydrodynamic parameters velocities turbulences, sediment transport concentration grain sizes parameters.
