Description :
Boulders of 2 coastal areas (Cape Skalas in southern Lakonia, Peloponnese; Cape Gerogombos on Paliki Peninsula in western Greece were surveyed within their topographical context using a laser scanner in combination with a DGPS. 3D reconstruction allows the determination of highly accurate volumetric data, as well as the extraction of further parameters, such as elevation above sea level, inclination and distance to the sea for each boulder. The results show that terrestrial laser scanning in combination with DGPS is capable to derive reliable parameters for wave transport equations. The combination of 3D model-based volume estimations and density measurements provide a better accuracy than achieved by conventional approximations, which are still the common method in scientific studies on boulder dislocation. The AA. found that volume data based on axes measurements together with density approximations result in a considerable overestimation of the mass of dislocated boulders.
