Summary

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). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km^2 study area. This data release includes videos of debris-flows and floods captured by high-definition cameras placed at four different locations along the study area at Chalk Cliffs during 2017. Near the Upper Station (Station 1) there are two cameras, one located at the bridge cross section at the channel (Bridge Camera) and another on the opposite side of the basin with a broad view of the channel (Wide-angle Camera). The third camera is located near Station 2 (Middle Camera), [...]

Summary

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). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km^2 study area. This data release includes videos of debris-flows and floods captured by high-definition cameras placed at four different locations along the study area at Chalk Cliffs during 2017. Near the Upper Station (Station 1) there are two cameras, one located at the bridge cross section at the channel (Bridge Camera) and another on the opposite side of the basin with a broad view of the channel (Wide-angle Camera). The third camera is located near Station 2 (Middle Camera), and the final camera (Firehose Camera) is located near the bottom of 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. The videos and their audio are used to record information on flow type and velocity of debris flows. They can also be used to interpret how the flow characteristics, such as sediment concentration, vary with time to compare to seismic observations.

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 debris flows and floods were captured by the four cameras. The videos can currently be viewed in the individual ‘Child item’ pages accessible below. The ‘Child item’ pages contain either flood or debris flow video files for each camera described above.
