Environmental risks and impacts of mountain reservoirs for artificial snow production in a context of climate change
Abstract
Mountain reservoirs are hydraulic structures established in recreational mountain resorts designed to provide a water reserve mainly used for the production of artificial snow. Their siting in high-altitude zones makes them highly specific reservoirs subjected to and inducing risks and impacts on their human and ecological environment. Based on in-depth bibliographic and field research, Cemagref has launched a study on mountain reservoirs. The present article aims to establish the current state of the risks related to mountain reservoirs and their impacts on the environment, placing the development of mountain reservoirs in their societal, social, and environmental contexts. It will then develop mountain reservoir risks and impacts, focusing on the specific risks and uncertainties to which these structures are exposed, and the different environmental impacts related to the construction and management of these reservoirs.
