Case study at a model site „Green Economy Park“ in Bremerhaven, Germany „Luneplate“: High resolution 3D subsurface models in flow modeling with a focus on climate resilience

The Luneplate in Bremerhaven consists largely of nature reserves and bird sanctuaries. The soils have a thick alluvial clay horizon. Climate change threatens the region through seasonal heavy rain events, but also through the drying out of clay soils and the spread of saltwater inland due to rising sea levels. The region has traditionally been primarily agricultural, and in the northern part there is an economic area that will be complemented by a carbon-neutral GreenEconomy Park.

The planners of the new business park want to take various measures, including the use of excess rainwater, the creation of compensation areas and infiltration basins to drain surface water. This should also prevent the organic-rich alluvial clay from drying out, reducing the risk of higher CO2 release. This pilot project on the Lune Plate will explore, as part of the Interreg Blue Transition project, how the region can be made more climate resilient through targeted groundwater management measures that are already planned, as well as new measures such as infiltration wells. Infiltration wells can reduce saltwater intrusion and dissipate heavy rainfall. A high-resolution 3D groundwater model is used to simulate the effects of these measures and estimate their impact on climate resilience. The aim of the project is to enter into a dialog with investors and project managers in order to realistically assess the impact of measures and make a meaningful contribution to climate resilience.
