The present paper discusses the first results of the sensitivity to roughness of a two-dimensional hydrodynamic to simulate flooding in particularly low lying areas. In such areas ,which lack well defined morphological boundaries , the characteristics and variation of the vegetation cover could also significantly influence the extent and hydraulic characteristics of the flood. This research is envisaged as the first step of a study of roughness characterization of the Lucanian Ionic coastal plain in relation to the type of cultivation present, based on data collected by a terrestrial laser-scanner. Such an analysis will lead to a reduction in uncertainties in the identification of flood risk linked to approximations in the choice of the roughness coefficient of the flood plain.
