The comparison between the model and the data for the wave height transformation of the short waves and the long waves (defined as waves with a frequency greater than $f_p/2$ and less than $f_p/2$, respectively) is shown in \autoref{fig:Boers_1C_default_fig1.eps}. 
The top dark blue line indicates the short wave height transformation, which should compare well with the measurements, except for details around the breakpoint. The green line and stars indicate the mean (steady) set-up which should be well-predicted, except in the trough region (x=21-25 m). The red lines and stars indicate the total (incoming and reflected) low frequency wave, which is slightly overpredicted in the shoaling zone (up to the breakpoint) and stays too large after that. 
The observational data is separated into incoming and reflected long wave components using an array of wave gauges (Bakkenes, 2002) and the numerical data has been separated into two components using co-located surface elevation and velocity information. The incoming long wave (cyan line) follows the observations (cyan stars) with a notable overprediction seaward of the breaking zone. The reflected long waves (black lines) match the observations (black stars) quite well.
