Predictions of long-term coastal evolution on decadal timescales are increasingly sought for adaptation planning in light of climate change and sea-level rise. Present and future needs demand the extension of process-based models beyond short-term time scales to assessment of long-term coastal changes. These models are already able to provide detailed analysis and prediction of morphological changes at short-term time scales. Still, further investigation is needed to bridge the gap between short-term hydrodynamic and transport processes, varying over hours to days, and morphological changes, often taking place over much longer periods. Thus, the importance of studying the medium to long-term (years to decades) morphological change and its effect on coastal sustainability stresses the need for new methodologies to support predictions over these time scales.
Explore process-based models with the aim to identify the best strategy to simulate long-term coastal evolution of sandy coasts;
Explore different approaches to schematize boundary conditions in order to be able to simulate long-term coastal processes;
Develop Duna and ShorelineS models further;
Create a solution for modeling long-term (years to decades) evolution of sandy coasts integrating marine and aeolian processes, and both cross-shore (1D approach) and longshore (oneline or coastline approach) processes;
Validate the developed approach.
