AbstractTo study potential impacts of climate change on aquifer recharge, this project has first relied on historical records of baseflows and groundwater levels to estimate statistical trends. Then, forecasts have been obtained with various numerical models and CRCM4 climate data for the 2041-2070 horizon. Modeling at six sites was carried out using either hydrogeological (HELP) or hydrological (HYDROTEL and MOHYSE) models, or both. Climate scenarios have allowed the comparison of simulated values of streamflow, baseflow, or recharge for past and future periods and trend results.
