Model of storm impacts on the high-altitude lake Muzelle
High-altitude lakes are not only subject to exacerbated atmospheric warming but also highly exposed to intense episodic weather events. The future of these ecosystems under climate change might not be appropriately forecasted by only climate change trends, i.e., warming, if episodic events and hydrological changes have the potential to deflect the seasonal trajectory of crucial physical and metabolic lake characteristics.
We combine paleo-ecology, low- and high frequency surveys and modeling to explore how hydrological changes due to climate change or hydropower affect the biogeochemistry of high-altitude lakes and reservoirs.
