The vegetation properties can be specified for multiple
species and can vary per species over the vertical to mimic a
mangrove tree. In XBeach a vegetation-file can be specified
that contains a file list with vegetation properties including
number of vertical sections, the height of a section (h), drag
coefficient (CD), number of plants per unit area (Nv), and plant
area per unit height (bv). To check the correct implementation
and applicability of XBeach we have included a comparison
with laboratory experiments in an Appendix.
