iCOASST – integrating coastal sediment systems James Sutherland HR Wallingford
theiCOASST project • Four year R&D project funded by Natural Environment Research Council (NERC) and supported by Environment Agency (EA) • Runs from 2012 to 2016 • Coordinated by University of Southampton
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 Map Maps 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’.
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
