\citet{Steetzel1987} describes a series of large scale experiments with revetments of different heights. The experiments are performed in the Deltaflume of Delft Hydraulics, now known as Deltares. A depthscale $n_d$ = 5 is used for all experiments \citep{Vellinga1986} and the initial profile in the flume correponds to the reference profile for the Holland coast. At the dune foot, which was located at 193m from the wave board and 3.80m above the flumes floor, a concrete revetment is applied that covers almost the whole dune face with a slope of 1:1.8. The lower end of the revetment is located at 2.5m above the flume floor. The location of the top of the revetment varied in each experiment. The tests were conducted with a constant water level of 4.2m and wave conditions that correspond to a Pierson-Moskowitz spectrum with $H_{m0}$ = 1.50m and $T_p$ = 4.20s. The sediment applied in the test had a median grain diameter of approximately $D_{50}$ = 210$\mu$m. An overview of the tests is given in \autoref{tab:experiments_H298}.

\textbf{Results morphology}\newline
The profile developments as measured and computed by XBeach are presented in \autoref{fig:T1_profile2} to \autoref{fig:T3_profile}. The upper panel shows the observed and modelled erosion profile and the lower panel shows the bed level change caused by the erosion/decomposition. The morphological indicators (Dune retreat, Erosion volume and Berm slope) are shown in \autoref{tab:H298_overview} for the three tests. Both the observed (obs) and modelled (xb) values for the morphological indicators are shown.

Next to the morphology also the hydrodynamics are validated. A comparison for the wave height is shown in \autoref{fig:T1_hydro}, \autoref{fig:T2_hydro},and \autoref{fig:T3_hydro}. Besides the wave height also the runup level was measured in the experiments. In \autoref{fig:T1_runup}, \autoref{fig:T2_runup} and \autoref{fig:T3_runup} the runup exceedance distribution is shown.
