Abstract Climate change impacts on the water cycle can severely affect regions that rely on groundwater to meet their water demands in the mid- to long-term. In the Lake Tana basin, Ethiopia, discharge regimes are dominated by groundwater. We assess the impacts of climate change on the groundwater contribution to streamflow (GWQ) and other major water balance components in two tributary catchments of Lake Tana. Based on an ensemble of 35 bias-corrected regional climate models and a hydrologic catchment model, likely changes under two representative concentration pathways (RCP4.5 and 8.5) are assessed. No or only slight changes in rainfall depth are expected, but the number of rainy days is expected to decrease. Compared to the baseline average, GWQ is projected to decrease whereas surface runoff is projected to increase. Hence, rainfall trends alone are not revealing future water availability and may even be misleading, if regions rely heavily on groundwater.

An assessment of the risk for groundwater pollution and vulnerability to pumping can help identify strategic groundwater bodies to define sustainable management measures of groundwater resources. In this paper, we propose a new method to make a preliminary estimation of the risk for groundwater pollution at the aquifer scale through the lumped turnover time index (T index). A new lumped index (L-RISK index) was defined to assess the significance of the risk for pollution at the aquifer scale. Both L-RISK and T indices were employed to calibrate a linear regression model that showed a good inverse correlation in the eight aquifers of the Upper Guadiana Basin (Spain). This novel method can be applied to analyze a wide range of aquifers with limited information in order to identify potential strategic aquifers. It also allows one to make a preliminary assessment of the impacts of climate change on L-RISK. The results showed a high variability of the T index in the eight aquifers (8–76 years). Three of them had significant greater mean T values, which could be considered to be the main strategic groundwater resources. In the future, the T index will increase between 8 and 44%, and the L-RISK will decrease in all aquifers (1–18%).
