Many ecosystem stressors are affected by hydrological processes and extremes. However, their interactions, in particular at large scales, remain poorly understood. This project will assess the interlinkages and cumulative effects of stressors over trajectories of several decades at the Central European scale. A groundwater model will be coupled to the large-scale hydrological modelling framework ReWaterGAP/WaterGAP3 to enhance the analysis of low flows and desiccation events. Major water quality parameters are modelled, and their spatio-temporal patterns and changes assessed over 70 years. The results are relevant for the upscaling of ecological findings and improve understanding of timing of degradation and recovery.
