iCOASST objective
• The objective of this programme is to improve our capability to predict long-term and regional scale change on the coasts and in our estuaries in the UK.
iCOASST approach
• To develop, integrate and implement a hierarchical modelling framework.
iCOASST system map
• Systems mapping to characterise the relationships between coastal landforms and interventions– Exchanges of sediment– Influences
iCOASST System Map
Hierarchy of• Landform complexes• Landforms• Interventions.
Identifies sediment pathways and influences
iCOASST System MapMaps can be analysed• Common linkages• Determines range of
behavioural models• Helps to identify
feedback.• Used to develop
consensus and understanding of coast as a system
iCOASST behavioural landform models
• A new generation of behavioural landform models– capable of coupled
application at regional scales – to resolve key feedbacks
between climate forcing, sediment supply, morphology, erosion and flood risk
iCOASST behavioural landform models
• NERC’s proposal stated that:‘Community modelling’ lies at the heart of model-based
science that seeks to understand environmental dynamics at a system level.
An OpenMI-coded modular format should be used to develop the concept of ‘community modelling’.
Generic cliff model
iCOASST behavioural landform models
• Used for modelling scenarios• Multiple runs to give a range
of outputs• Anticipate likely range of
outcomes• Influence coastal
management
iCOASST coastal area models
• Coastal area models– Quantitative analysis of
sediment pathways – Particularly large-scale
exchanges of fine sediment
– supported by empirical analyses of shelf bathymetry and substrate
