Congratulations to Elian Lüthy that has been granted the Culmann Fonds Award 2021 from ETH for her outstanding Master thesis entitled: “What are the Pathways? A method to assess habitat shifts for larvae during hydropeaking”. In this study, Elian developed a novel tool for modelling spatial and temporal shifts in suitable habitats for Brown trout larvae during hydropeaking events. This tool can serve as a complementary approach to the set of hydrological and ecological indicators available in the Swiss guidelines for hydropeaking mitigation. Elian’s work was developed in partnership with Kraftwerke Oberhasli AG (KWO), a Swiss hydropower company that has contributed to developing mitigation measures for hydropeaking impacts.
