Helping the Berlin-Brandenburg region adapt to climate change impacts

Groundwater and surface water modelling for the INKA BB project

Actual climate research results shows that, due to climate change, Germany’s Berlin-Brandenburg region will face a slight reduction in annual rainfall in the future, along with a significant increase in temperature-related potential evaporation. Both these factors will have a negative effect on groundwater recharge, which influences groundwater levels. As part of the INKA BB project, we modelled future groundwater flow and recharge in the region. In so doing, we were able to optimally visualise the future impacts on groundwater levels and quantify the deficits in water availability against the background of reduced groundwater recharge. Our study is helping authorities to objectively evaluate potential measures to counteract the future impacts of climate change on groundwater levels in the region.
