BGS’s coastal modelling capabilities are built around advanced, process‑based tools that simulate how coastlines change over time in response to environmental forces and human activities. At the core of this work is Coastal Modelling Environment (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 quasi‑3D simulations to assess coastal evolution under varying wave conditions, sediment supply and sea‑level scenarios. Using such tools, we can evaluate how coastlines may respond to storms, gradual sea‑level rise and alternative management approaches. The resulting quantitative insights help inform coastal planning, risk assessments and long‑term adaptation strategies.
A major area of research within BGS’s programme is the development of reduced‑complexity coastal morphodynamic models, such as the Coastline Evolution Model (CEM). These models capture the emergent behaviours of coastal systems over multi‑decadal 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 mixed‑sediment 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.
