BGSʦs coastal modelling capabilities are built around advanced, processʦbased tools that simulate how coastlines change over time in response to environmental forces and human activities. At the core of this work is (CoastalME), a flexible framework that integrates representations of beaches, cliffs and engineered structures to explore how different coastal landforms interact. CoastalME supports both 2D and quasiʦ3D simulations to assess coastal evolution under varying wave conditions, sediment supply and seaʦlevel scenarios. Using such tools, we can evaluate how coastlines may respond to storms, gradual seaʦlevel rise and alternative management approaches. The resulting quantitative insights help inform coastal planning, risk assessments and longʦterm adaptation strategies.
A major area of research within BGSʦs programme is the development of reducedʦcomplexity coastal morphodynamic models, such as the (CEM). These models capture the emergent behaviours of coastal systems over multiʦdecadal timescales, exploring how patterns of erosion, deposition and sediment exchange develop from the interplay of physical processes. By representing sediment transport, wave dynamics and landform feedbacks in an integrated way, they enhance understanding of vulnerability and resilience across sandy and mixedʦsediment coastlines.
Combined with field measurements and observational data, our modelling capabilities provide society with robust scientific tools to anticipate and manage coastal change. By exploring future scenarios and testing different intervention options, these models support sustainable coastal planning, help protect communities and critical infrastructure, and strengthen longterm resilience in the face of erosion, flooding and sealevel rise.
