Repeat observations of four debris-flow fans in south-western British Columbia, Canada, were made using a UAV-lidar system. Detailed measurements of deposit thicknesses and volumes have been generated from the data. We present channel measurements and characteristics for one of the sites to demonstrate the utility of the repeat lidar scanning technique to provide insights into where avulsions occur during debris flows. Through continued monitoring, we plan to obtain greater detail on a wider variety of events and the characteristics of avulsion locations.
