The Institute for Coastal Systems conducts research from physical, ecological and socio-economic perspectives on coastal system change due to climate change and use. We develop prediction methods and future scenarios for coastal systems and their resources, using coupled complex mechanistic and statistical models, as well as state-of-the-art AI methods. By developing digital twins of the coastal environment and providing our reconstruction and future scenarios, we support the sustainable and safe use of coastal systems and create a scientific basis for future-oriented coastal management. With our research, we provide scientific and methodological support for decision-making processes in public and private sectors.
