Abstract:
Objectives (1) Mapping flow and sediment dynamics in the Spöl river using high resolution geomorphological techniques (e.g. UAVs with digital image acquisition and thermal imaging, laser scanning, structure from motion); (2) Experimentation with e-flows in BACI designs to observe impacts on multiple ecosystem properties; (3) Link geomorphological dynamics with functional properties (sediment metabolism)
Expected results (1) New understanding of geomorphic and sediment response to flood flows in hydropower regulated rivers; (2) Driving role of abiotic habitat in ecosystem functional dynamics (e.g. sediment metabolism via dissolved oxygen sensors); (3) Knowledge of links between flow, habitat and invertebrate production
Abstract: Freshwater ecosystems across the world are facing the pressure of multiple stressors, undergoing an alarming ecological degradation. The exploitation of hydropower potential of rivers has substantially altered natural flow and sediment regimes, adding to stressors due to other human activities. Experimental floods (EF) are operational measures designed to restore flow variability and mitigate dam impacts on rivers. Flow-sediment interactions during EF represent strong ecosystem drivers, influencing nutrient dynamics, and metabolic and functional properties. Thus, it is relevant to understand how different sediment inputs influence abiotic and biotic responses to EF.
