Simulating two-phase debris flows in HEC-RAS at Hummingbird Creek, British Columbia, Canada by Horita Kathleen

“…Presented herein is the modelling for a debris flow hazard assessment for Hummingbird Creek, British Columbia, Canada. Model calibration best matched the observed debris flow deposit when the coarse front and hyperconcentrated flow were modelled separately in two phases allowing for separate flow rheologies to be used for the front and the tail of the debris flow, and allowing for deposition between phases. …”
