Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, 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 one of the high-definition cameras at the monitoring site in Chalk Cliffs, CO. This camera (Bridge Camera) is located at Station 1 which is at the bridge cross section at the channel. The attached figure "station_and_camera_locations.png" provides an overview figure with the location of the four cameras and three stations along the channel.
Video recording for all cameras is triggered using a rainfall threshold (Michel et al., 2019). The complete videos for all the cameras are downloaded manually during site visits. More detailed information about the cameras and settings used can be found in the metadata file under "Process steps" in "Data quality information." During 2017, several floods were captured by the 'Bridge Camera'. The videos for all floods captured by this camera along with the dates they were captured can be found in the attached zip folders.
