\chapter{Model comparison}

In this chapter, XBeach is compared to results obtained from other models. The comparisons are currently focused on the DUROS+ and D++ \citep{Vellinga1986,DelftHydraulics2006,Deltares2010} models that are used for the detailed assessment of dunes along the Dutch coast. Comparisons with other models like DurosTA \citep{Steetzel1993} are made throughout the report and are not discussed specifically in this chapter.

\section{Field applications}

In this section, DUROS+ \citep{Vellinga1986,DelftHydraulics2006} and D++ are \citep{Deltares2010} compared with XBeach based on field applications. Comparisons are made based on erosion volumes and retreat distances, since these are the main parameters of interest in dune safety assessment.
