\chapter{Morphological laboratory tests}

In this chapter, the performance of XBeach is compared to results obtained from physical model tests performed in a variety of experiments. Research took place at different laboratory scales, mainly depending on the size of the facility used. 

The accuracy of XBeach is quantitative verified for three indicators of the morphology \citep[see][]{Deltares2020_par}. The dune erosion above storm level, foreshore slope and dune retreat are considered as morphology indicators (see \autoref{fig:overview_BOI_ds}, \autoref{fig:overview_BOI_erosion} and \autoref{fig:overview_BOI_slope}). The definition of these indicators is given in \autoref{app:MorphologyIndicators}.  The quantities computed with XBeach are indicated with  $xb$ and the observed quantities are indicated with $obs$.
