Dendrochronological analysis of past hydro-climatic variations in La Grande river complex in Northern Quebec
International audience In order to retrace the evolution of the hydrological regime parameters with time, we have reconstructed the main hydroclimatological variables used in forecast models. The study was conducted in the region of the James Bay hydroelectric complex of La Grande. Trees occupying s...

International audience In order to retrace the evolution of the hydrological regime parameters with time, we have reconstructed the main hydroclimatological variables used in forecast models.

A calibration period with instrumental data is essential and it is also important to verify the models relating rings to climate with independent data.
