    We show the effects of both climate and land use changes on long term groundwater recharge. The study was conducted in the context of a safety assessment of a near-surface disposal facility for low and intermediate level waste; this includes estimating groundwater recharge for the next millenia. Climate change impact on groundwater recharge was simulated using HYDRUS-1D and weather time series from so-called analogue stations. Results showed that transition to a warmer climate is expected to yield a decrease in groundwater recharge. For land use change impact on groundwater recharge in the Nete catchment, conversion to crop (maize) and coniferous forest resulted in respectively the highest positive (recharge increase by 31%) and negative (recharge decrease by 42%) sensitivities. Further improvements of the method may consider correlation and feedback between combined land use change and climate change.
