Hydrological reconstruction from tree-ring multi-proxies over the last two centuries at the Caniapiscau Reservoir, northern Québec, Canada
International audience s u m m a r y The objective of this study was to reconstruct 200 years of spring (Q spr), summer (Q sum) and annual (Q ann) water supply variability at the Caniapiscau Reservoir in a remote area of northern Quebec. This region which is a key hydropower region of North America...

International audience s u m m a r y The objective of this study was to reconstruct 200 years of spring (Q spr), summer (Q sum) and annual (Q ann) water supply variability at the Caniapiscau Reservoir in a remote area of northern Quebec.
