AbstractAn assessment of groundwater recharge is performed for the Portneuf Regional County Municipality, as part of a regional hydrogeological mapping project. This assessment is based on the compilation of meteorological and hydrometric data for the period from 1973 to 1992. These data are interpreted by hydrological modelling. The CEQUEAU hydrological balance matrix model is applied to the Portneuf River drainage basin. The average groundwater recharge calculated for the entire drainage basin is 299 mm/year for average precipitation of 1174 mm/year.
