Debris-flow Video Files for Bridge Cameras (Upper Station), Chalk Cliffs, Colorado, USA, 2019

Metadata Updated: July 6, 2024

Chalk Cliffs, located 8 miles southwest of Buena Vista, CO, is one of the most active debris-flow areas in the state (U.S. Geological Survey). This "Child item" page includes videos of floods captured by two of the high-definition cameras at Chalk Cliffs which are located at the Upper Station. This station drains an area of 0.06 km^2 and was used to monitor flow properties and triggering conditions in the headwaters of the study area. It was equipped with two rain gauges, a laser distance meter to measure flow stage, two geophones to record ground vibrations, a force plate to measure the basal impact forces of the flow, and two downward looking video cameras to record flow characteristics (Kean et al., 2020).The two cameras at the Upper station are mounted in stereo approximately 92 cm apart and view the flow immediately upstream of the cross section where flow stage, basal force, and one set of ground vibrations are measured. The observations from these cameras aid in the interpretation of time series data at the cross section and help constrain flow velocity, sediment concentration, and particle grain size. The setup of the two cameras at the Upper Station can be seen in the attached image "Upper_station_setup.JPG". Also see figure “station_and_camera_locations.png” for the location of the cameras and stations at Chalk Cliffs. Camera video recording is triggered when the rainfall intensity exceeds a threshold (see Michel et al., 2019). Video files for the camera were downloaded manually during site visits. More detailed information about the camera and settings used can be found in the metadata file under “Process steps” in “Data quality information.” The following citations relate to reports that provide background information for this data release: • Kean, J.W., Smith, J.B., and Coe, J.A., 2020, Debris-flow monitoring data, Chalk Cliffs, Colorado, USA, 2014: U.S. Geological Survey data release, https://doi.org/10.5066/P9MUWDFN. • Michel, A., Kean, J.W., Smith, J.B., Allstadt, K.E., Coe, J.A.
