An illustration of low wave energy dynamics for a specific morphology... Under present-day conditions, berm rollover is a common phenomenon, often occurring without major foreshore retreat. However, further sea level rise will increase tidal exchange to wetland basins. Once large enough, breaching can lead to wetland infill, with much more rapid and substantial foreshore response.
For those practicing in this field, XBeach has provided some improvements over 'conventional' profile modelling. However, are the tools yet ready for the next 'step change' in morphodynamics...?
