Abstract: AbstractThis report describes a method of extracting vegetation conditions and topo‐bathymetric data of rivers using airborne LiDAR with near‐infrared and green pulsed lasers. Parameters related to flow resistance attributable to vegetation in rivers were found using point cloud data of LiDAR with support from supervised classification. Comparison of data obtained from simulations and observations was used to assess the applicability of the proposed method for examination of lower Asahi River flooding that occurred in Japan in September 201...
