Abstract
Different tools and models are nowadays available for the identification of flood-prone areas. The application of these approaches is strongly influenced by the availability of site-specific hydrological information. As an example, a combined scheme of hydrological and hydraulic models for the definition of flood events is reliable when there are lots of hydrological and hydraulic information, which makes it difficult to be exploited in ungauged catchment. In this context, DTM-based geomorphological methods are able to provide a rapid identification of a flood susceptibility where the availability of data directly observed in situ is limited. In this study we investigated ability and performances of two morphological descriptors in defining flood exposure with respect to accuracy of morphological information in the context of ephemeral streams located in Puglia region (Southern Italy). Results showed an influence of data resolution on descriptors performances, providing an additional contribution to the investigations carried out in similar areas during last years.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
