The nine vegetation parameters—three for each of the three
layers that had to be estimated or measured on the basis of the
requirements of the XBeach model—are the diameters (bv),
densities (Nv) and heights (ah) of the roots, stem, and canopy.
The characteristics ofRhizophorasp. andSonneratiasp. are
fully described by Narayanet al. (2011) for mangrove in India,
which we have adopted here. We defend applying these
parameters for mangrove species in Vietnam because of the
similarities between the mangrove species in the Mekong Delta
and those in India (includingSonneratiasp. andRhizophora
sp.) (Table 3).
