Modeling the water cycle in past, present, and future offers the opportunity to estimate long-term changes in the water balance and to set them in an actual context. Also, changes in extremes can be investigated with hydrological modeling to detect future hotspots where high damage due to extremes can be expected. This information is extremely valuable for different stakeholders like policymakers or non-governmental organizations so there is a tremendous need for high-quality information.
In our research we are enhancing the hydrology model of the global model framework WaterGAP3 to simulate the global water resources more accurately.
