Meanwhile it is recognised that beach morphodynamics is not a regular process and is strongly correlated to meteorological conditions. A series of 25 terrestrial laser scans of a beach experiment is analysed, obtained during a time period of 88 hours, characterised by changing weather conditions including strong wind and rain. It is shown that after a conversion to a cylindrical grid, different deformation regimes can be identified and rates of elevation changes below 1 mm per hour can be detected. Simultaneously, an analysis of distances between targets through time demonstrates the sensitivity of the used measurement set-up to the harsh weather conditions.
