Example morphology data. (a) An example beach profile as measured by the mechanical profiler (black) and the swash zone profile obtained from the Lidar data (blue). (b) Separation of bed (black dots) and swash data at x = 253.8 m (blue), x = 255.3 m (red) and x = 256.8 m (orange) for an example section of data. The mean bed elevation between each swash event is shown in white. (c) Bed elevation change relative to the initial profile in the swash zone at the wave-by-wave timescale. (d) Beach profile data showing the evolution of the sand beach and dynamic revetment modified from Bayle et al.6. The revetment surface is marked with a thicker line.
