Monthly Freshwater Runoffs of the St. Lawrence at the Height of Quebec City
METHODOLOGY
The monthly mean run off is estimated using an empirical relationship between the St. Lawrence River discharge and the water-level at Neuville with the Bourgault and Koutitonsky (1999) method. The uncertainty is +/- 2100 m3/s at 95%.
