Impact of land cover changes on <scp>Long‐Term Regional‐Scale</scp> groundwater recharge simulation in cold and humid climates

In cold and humid climates, warming temperatures will result in longer growing seasons, leading to land cover changes that could have long-term impacts on groundwater recharge (GWR), addition the direct of climate change. The objective this study was therefore investigate whether (LC) need be considered when simulating regional-scale potential GWR climates by (1) quantifying how LC impact simulated (2) combined future changes. Using region southern Quebec (Canada) as a case water budget model, work proposes an innovative coupling change scenarios specific conditions simulate spatially distributed transient over 1951–2100 period. results showed including simulations produced statistically significant increases compared using constant through time (average +13 mm). Massive afforestation taking place agricultural lands for one scenario chains (RCP4.5) increased reducing runoff during snow-dominated period − 17 also more sensitive included intense Additionally, spatial distribution influenced their GWR. Considering methodology computationally feasible entirely transferrable new CMIP6 ensemble, should systematically resources simulations.
