IAHR_5_S6.1: Hydropeaking in regulated rivers – from hydraulic analysis to design of mitigation measures

Convenor: Christoph Hauer (University of Natural Resources and Life Sciences, Vienna), Davide Vanzo (ETH Zurich), Jo Halleraker (Miljodirektorat), Martin Schletterer (TIWAG, Austria)

Hydropeaking – the artificial increase and decrease of discharge and corresponding water levels in rivers – is characterized by steep rising and falling limbs of hydrographs based on the operation of storage hydropower plants to generate electricity on the energy demand. The proposed special session has been conceived under the awareness that the dynamics of hydropeaking and its sustainable management strategies need to be grounded. The special session deals with (i) basic research and (ii) implementation studies with focus on hydraulic, hydro-morphological / sedimentological interactions and technical options for mitigation of hydropeaking.
