Short summary

For two Austrian catchments we simulated discharge and nitrate-nitrogen (NO₃-N) considering future changes of climate, land use, and point source emissions together with the impact of different setups and parametrizations of the implemented eco-hydrological model. In a comprehensive analysis we identified the dominant sources of uncertainty for the simulation of discharge and NO₃-N and further examined how specific properties of the model inputs control the future simulation results.
