AbstractGroundwater-surface water interactions impact aquifer recharge and groundwater levels, and are in turn affected by direct and indirect anthropogenic factors, including pumping and climate change. In the present study, a coupled numerical model was implemented for a small (8 km2) catchment in Nova Scotia to investigate how the hydrological response is affected by climatic changes. The model was calibrated for the year 2005 based on streamflow and groundwater data. The Canadian Regional Climate Model (CRCM4) was then used to generate 30-year climate forecasts. The simulation outputs were statistically analyzed using a non-parametric test to detect trends.
