Monitoring and modelling of extreme events

in the Elbe estuary and the German Bight

ElbeXtreme, led by Prof. Dr. Eric Achterberg ( GEOMAR Helmholtz Helmholtz Centre for Ocean Research Kiel ), focuses on extreme hydrodynamic and ecological events in the Elbe Estuary and the German Bight.

Why do we do this?

Extreme events such as floods, droughts, heatwaves and storm surges pose significant risks to coastal ecosystems and human communities. Global climate change and ecosystem degradation are increasing the frequency and intensity of these events. The Elbe Estuary and the German Bight are vulnerable to extreme hydrodynamic and environmental events such as storm surges, heatwaves, floods and pollution events due to their geographical location and intensive use. These events can cause significant damage to water quality and ecosystems and affect biodiversity.

Our goal

ElbeXtreme aims to better understand extreme events such as storm surges, heatwaves, floods and pollution events in order to strengthen the resilience of coastal ecosystems and human communities. By working with stakeholders such as local communities, national authorities and industry and building a comprehensive information and decision support system, the project contributes to increasing the resilience of the region and promotes dialogue between science, policy and practice to address the challenges in the Elbe Estuary and the German Bight.

Our objectives in detail: 1. Recording and analysis of extreme events: Systematic recording and analysis of historical and current data on extreme hydrodynamic and ecological events in the Elbe Estuary and the German Bight. Assessment of the impacts of these events on the ecosystem and human activities. 2. Model development: Development and validation of hydrodynamic and ecological models to predict extreme events. Integration of climate models to assess future risks and adapt the models to climate change. 3. Risk reduction strategies: Development of strategies and measures to reduce risk and adapt to extreme events. Collaboration with local authorities and stakeholders to implement these strategies. 4. Information and decision support systems: Development of an information and decision support system that provides real-time data and forecasts. Promotion of dialogue and cooperation between science, politics and practice to jointly address the challenges.

How do we do that?

We investigate the impacts of extreme events on the transport of carbon, nutrients and pollutants as well as the consequences for biodiversity and ecosystem functions. We collect valuable data through innovative technologies and monitoring systems. Using biogeochemical models and in close cooperation with stakeholders, we develop effective adaptation and mitigation strategies that improve the protection and resilience of the affected areas.

ElbeXtreme will apply state-of-the-art methods of data collection and analysis, including remote sensing, in-situ measurements and numerical modelling. Historical data will be used together with current observations to calibrate and validate models. Climate models will be integrated to simulate future scenarios. The interdisciplinary approach ensures that both scientific and societal aspects are taken into account.
