Morphodynamic changes at sandy coasts, as are dominant in The Netherlands, are typically monitored at yearly intervals by means of LIDAR. Meanwhile it is recognized that beach morphodynamics is not a regular process but is strongly correlated to meteorological conditions. A time series of 14 terrestrial laser scans of a beach experiment is analyzed, obtained during a time period of 88 hours characterized by changing weather conditions including strong wind and rain. It is shown that after a conversion to a suited spherical grid, different deformation regimes can be identified and that elevation changes rates below a millimeter an hour can be detected.
