Temporal variability of beach morphology is driven by sediment
transport in cross-shore and/or longshore directions. Longshore beach
change is mainly characterised by long term variability of shoreline position,
beach rotation and development of rhythmic features. On the
other hand, cross-shore change is characterised by changes in the
shape of cross-shore profile and the area of beach cross section in
time. While longshore beach changes have significant impacts on the
medium to long term beach position and orientation, cross-shore
change occurs over awide range of timescales and can have detrimental
impacts on the stability of natural and man-made sea defences, coastal
eco-systems, infrastructure and safety. In this study we specifically
focus on morphodynamic change in the cross-shore direction as crossshore
beach profile change spread over a range of time scales and is
crucial to short-medium term beach stability and storm response, stability
of coastal defences, wave overtopping and coastal inundation
transport
