The decomposition of the water level into incident and reflected wave components is usually a necessary step in numerical or flume studies, as most design variables (overtopping, run-up) are linked to the incoming wave characteristics. Thus, utilizing an appropriate wave reflection analysis is critical for the analysis of such experiments. To this end, scaled experiments with a model salt marsh were carried out at the flume of the Hydraulic Engineering lab of the Delft. Two SICK LMS511 lidar laser scanners (LS) were used to record a dense grid of water levels along the wave flume. At the conference, we will showcase our findings by comparing the results of three wave reflection analyses applied on the LS data, in terms of incoming and reflected wave characteristics, as well as spectrum transformation, for a range of hydrodynamic conditions and geometrical set-ups.
