AbstractThis paper presents an adaptation of Optech¿s bathymetric LiDAR technology to sediment distribution mapping in shallow coastal areas. The study site was a shoreface area of moderate wave energy with siliciclastic sediment along the north shore of the Baie des Chaleurs in Québec (Canada). Using IDL (Interactive Data Language), we have developed an application for classification and mapping of bottom sediments. This involves a statistical analysis of morphological features of the seafloor LiDAR return signal, combined with some seafloor morphological parameters. This study demonstrates that, despite limitations, it is possible to produce high-resolution sediment distribution maps in regions of sand and gravel seabed using this bathymetric LiDAR technology.
