\chapter{Field validation}
\label{sec:field_validation}
In total, nine field datasets, comprising 69 cross-shore profiles, are are available with data on either hydro- or morphodynamics of a storm. In total, two profiles are available purely for the hydrodynamic validation and 60 for the morphodynamics validation. In addition, seven transects (Egmond aan Zee) are used for both hydrodynamic and morphodynamic validation. \autoref{tab:overview_cases} provides an overview of these cases. The cases cover a variety of wave and water level conditions, profiles shapes and grain sizes, as explained below. This variation is strongly related to the variation in geographical location of the cases studies: most locations are at several locations along the North Sea coast, but Case 2 is along the French Atlantic coast and Case 5 along the East coast of the USA. Each case comprises 1 to 30 cross-shore profiles for which validation data are available and a 1D BOI-XBeach simulation is set up. As far as possible, the chosen profiles are at a more-or-less alongshore uniform location to limit processes in the alongshore direction that affect the 1D validation results. For the morphodynamic validation, Case 9 (‘Holland 1953’) could only be used for a general validation (focus on the order of magnitude of dune erosion) due to limitations in available data, but this is still valuable since this storm resulted in the largest recorded dune erosion volumes along the Dutch coast. In the following sections of this report, each individual field case is described in more detail. This comprises a case description and a comparison of the latest XBeach model results with the measurements.
