In the sixth video of seven, Dr. Chris Hopkinson discusses the uses of LiDAR in hydrological modelling. Optical data and LiDAR data can be combined for detailed vegetation classification. Wind and solar aspects can be interpreted from LiDAR (e.g. aerodynamic roughness). Cross sections information is a place where LiDAR can significantly improve hydraulic modelling. Although surveyed cross sections provide precise elevation data the advantage of LiDAR is to fill in cross sections where regular surveying would be expensive. Likewise in multi-channels, LiDAR slope data would help in defining multiple channel flow. Flood inundation scenarios are mentioned at the end of the video.
Dr. Chris Hopkinson's presentation was part of the University of Lethbridge's workshop on LiDAR/SAR, June 26, 27, 2014.
