Debris flow monitoring at Chalk Cliffs, CO (2017)

The USGS and its cooperators have installed debris-flow monitoring equipment in the largest drainage basin at Chalk Cliffs, CO. Data collection at this site supports research on the hydrologic factors that control debris-flow initiation, entrainment, and flow dynamics.

Post-wildfire debris flow: 2016 Fish Fire, Las Lomas Canyon

The June 2016 Fish Fire burned over 12 km^2 in Los Angeles County, California. After the fire, the USGS installed an automated rain-triggered camera to monitor post-wildfire flooding and debris flow in a small canyon above the Las Lomas debris basin in Duarte. This video shows the peak flow triggered by an intense rainstorm on January 20, 2017.

Post-Wildfire Debris Flood: 2016 Fish Fire, Van Tassel Canyon, CA

The June 2016 Fish Fire burned over 12 km^2 in Los Angeles County, California. After the fire, the USGS installed an automated rain-triggered camera and laser stage gage to monitor post-wildfire flooding and debris flow in Van Tassel Canyon near Azusa. This video shows the peak flow triggered by an intense rainstorm on January 20, 2017.
