Las Lomas Hillside Lidar
This data release contains point clouds obtained from three terrestrial laser scanner (TLS) surveys of a hillslope (NAD 83/11 N/ 412828E/ 3780128N) burned by the 2016 Fish Fire in the
San Gabriel Mountains, CA, USA. The TLS surveys were completed with a Leica ScanStation C10. The first survey was made on 19 November 2016 prior to the first post-wildfire rainstorm. The second survey was performed on 5 January 2017. Two runoff-generating rainstorms occurred between the first and second surveys. The two rainstorms had peak fifteen-minute average rainfall intensities of 27 mm/h and 10 mm/h, respectively. The third survey was performed on 22 February 2017, following five additional runoff-generating post-wildfire rainstorms. Peak fifteen-minute average rainfall intensities for the five rainstorms were 8 mm/h, 11 mm/h, 16 mm/h, 25 mm/h, and 38 mm/h, respectively. Maps of hillslope erosion derived from the TLS data can be used to document hillslope erosion resulting from these two sets of rainstorms, including the initiation and growth of a substantial rill network. Additional details and a description of the study site can be found in the journal article: Hui T, McGuire LA, Rengers FR, Kean JW, Staley DM, Smith JB. Evolution of debris flow initiation mechanisms and sediment sources during a sequence of post-wildfire rainstorms. Journal of Geophysical Research. 2018.
