From 1974 to 1975, 58 model experiments for the derivation of scale relations are performed in the Wind Flume of Laboratory De Voorst in the Netherlands \citep{VanDeGraaff1976}. Four different depth scales are used in these experiments: 150, 84, 47 and 26. Also, two different sediment diameters are used: 225$\mu$m and 150$\mu$m. During all experiments, the dune is exposed to a significant wave height of 7.6m and a constant maximum surge level of 5m+NAP on prototype scale.

The flume had a length of approximately 100m and a width of 4m. The flume was subdivided in four parts with a width of 1m each. Using this configuration, it was possible to perform four experiments at a time. All experiments are therefore considered to be one-dimensional.

Among the 58 experiments available, 6 experiments were calibration experiments, another 6 experiments are performed on a very small scale (150), in 4 experiments the profile development was disturbed and in another 8 experiments a variable surge comparable with the 1953 storm surge was used. These experiments are excluded from the skillbed as for now. The 34 experiments left are presented in \autoref{tab:experiments_M1263I}.

The profile development computed by XBeach is compared to the measurements for all 34 experiments. One of these comparisons is shown in \autoref{fig:m1263_1_random_profile}. For all other experiments, only the resulting Brier Skill Score is presented in \autoref{fig:Windflume_M1263_I_bss}.
