This database contains the simulation of potential groundwater recharge (GWR) with a 500 m x 500 m resolution and a monthly time step over southern Quebec for the 1961-2017 period. These data were simulated using the HydroBudget model (HB; Dubois et al., 2021a, b) and are presented in Dubois et al. (2021c). The simulation was performed at UQAM by the team of Pr Marie Larocque’s research Chair on Water and land conservation (Chaire Eau et conservation du territoire), as part of a project funded by the Quebec Ministry of the Environment (Ministère de l’Environnement et de la Lutte contre les changements climatiques - MELCC).
The study area is located in the Province of Quebec (humid and cold climate; Canada), between the St. Lawrence River and the Canada–USA border and between the Quebec–Ontario border and Quebec City (35 800 km2). The study area is divided into 140 656 cells of 500 m x 500 m.
The simulation results are sorted in files by year that contains for each grid cell the monthly values of simulated vertical inflow (VI; sum of observed rainfall and simulated snowmelt – mm), average temperature (°C), simulated runoff (runoff + excess runoff – mm), simulated actual evapotranspiration (mm), and simulated potential GWR (mm).
