The bridge pier and the land area were measured by UAV laser, and the acquired point cloud data was synthesized with the underwater point cloud data. By conducting scouring surveys using drone-mounted green laser surveying, it is possible to check the riverbed conditions from a safe location on the ground, enabling highly safe scouring surveys. We were able to acquire data up to a depth of 3.5 meters for the rivers surveyed this time, and we were able to confirm the scouring situation with three-dimensional data.
