Advances in Debris Flow Science: Observations, Modeling, and Beyond
Session ID#: 247665
Session Description:
Debris flows are one of the most destructive forms of mass movement because of their high velocity, long runout and ability to transport large caliber material. Debris flows can initiate during rainstorms and earthquakes. Their likelihood and size can be influenced by critical zone processes operating over geological time as well as more abrupt landscape disturbance due to wildfire or anthropogenic changes (e.g., logging, mining). Debris flows pose a hazard to life and infrastructure, and over centuries and millennia they play critical roles in shaping steep landscapes. We propose a session that highlights recent progress in debris flow science including topics such as debris flow mechanics (initiation, transport, and deposition), debris flow modeling, the geomorphic consequences of debris flows on landscape evolution, and communication of debris flow hazards. All studies focusing on observations and modeling for debris flows and related mass movements, including landslides and rockfalls, are encouraged to submit.
