BEACH REPLENISHMENT

Calculation of the sand volumes through drone and photogrammetry Castiglione della Pescaia, Grosseto, 2020

Within this project, part of the annual plan of costal replenishment of Castiglione della Pescaia, I monitored the volumes of sand taken from the seafloor and deposited on the beach waiting to be spread. In order to have an accurate, simple and easy estimate of the sand accumulated by the dredger we did many drone flights taking many photos of the area. The pictures were elaborated creating a dense point cloud and a DEM, through this process we were able to calculate the sand volumes. The results were exported in klm and kmz, native formats of Google Earth, and sent to the construction company that was able to verify via geo-referenced models the real volumes moved by the dredger and compare it to the project one in the most accurate way.
