From top to bottom, series DD1, D2 and D3. The upper panel in each figure is cumulative change relative to initial profile (every 15 minutes of waves at varying tidal heights, always low to high and back to low). Red indicates relative accretion and blue indicates erosion. Y axis increase landwards, and profile number corresponds with increasing time.
Qualitatively, a similar pattern emerges - morphological change is assymetric with the tide, and becomes more so when the lagoon levels become high or low. In addition, the consistent theme is one of sediment convergence, especially on the ebb tide (presumably when the groundwater table is super-elevated?), and positive feedback - once features form, they grow. Series DD1 and D2 have nice examples of berms stranded by the ebbing tide. Series D3 has the best example of sedimentation through sediment convergence
