The objectives of this work are a morphodynamic characterisation of Parco del Circeo (southern Lazio region) beach-dune system and an integration of different topographic datasets used to analyse and monitor the seasonal variability of the study site. The seasonal morphological analysis of the beach-dune system has been performed with topographic surveys using Differential GPS and LiDAR sensor. DGPS surveys have been performed from March 2009 to January 2010 along cross-shore transects representative of the morphodynamic variability of the system. Hawk Eye II LiDAR survey has been carried out between Torre Astura and Circeo Promontory in a costal area of 40 km2 on 9th and 10th May 2009. Data acquired allowed the extraction of the dune perimeter from LiDAR dataset, the extraction of beach-dune cross-shore profiles from the DGPS dataset and a combined analysis of both LiDAR and DGPS datasets. Results from the seasonal monitoring activities outlined the most significant morphological variations along the beach-dune profile. The combined analysis between LiDAR and DGPS datasets was useful to validate the surveys and to outline the short term dynamics (daily scale) of the dry beach.

Abstract
The objectives of this work are a morphodynamic characterisation of Parco del Circeo (southern Lazio region) beach-dune system and an integration of different topographic datasets used to analyse and monitor the seasonal variability of the study site. The seasonal morphological analysis of the beach-dune system has been performed with topographic surveys using Differential GPS and LiDAR sensor. DGPS surveys have been performed from March 2009 to January 2010 along cross-shore transects representative of the morphodynamic variability of the system. Hawk Eye II LiDAR survey has been carried out between Torre Astura and Circeo Promontory in a costal area of 40 km2 on 9th and 10th May 2009. Data acquired allowed the extraction of the dune perimeter from LiDAR dataset, the extraction of beach-dune cross-shore profiles from the DGPS dataset and a combined analysis of both LiDAR and DGPS datasets. Results from the seasonal monitoring activities outlined the most significant morphological variations along the beach-dune profile. The combined analysis between LiDAR and DGPS datasets was useful to validate the surveys and to outline the short term dynamics (daily scale) of the dry beach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
