On Saturday, November 10th, 2018, the Southern California and Inland Empire Chapters of AEG (Association of Environmental & Engineering Geologists) held a seminar addressing Debris Flow Hazards. The seminar was hosted by the California State Polytechnic University, Pomona, Geology Department, at the Kellogg West Conference Center. Most noteworthy, topics included:
- GEER Activities following Montecito Debris Flows – Richard Ortiz
- Case Studies of Post-Wildfire Debris Flows in CA – Joseph Gartner
- Localized Intense Rainfall Documented by NEXRAD Weather Radar as Triggering Mechanism – Jeffrey Keaton
- Mechanics of Debris Flows – Paul Santi
- The Thomas Fire Debris Flow in Montecito, CA – The Real Fire an Fury: Aftermath, Clean-up, and Lessons Learned – Christian Doolittle
- Flexible Debris Flow Nets for Post Wildfire Debris Mitigation in the Western United States – William Kane
- Geotechnical Disaster Planning Using Oblique Aerial Photography to Improve Profits, Limit Losses, and Mitigate Liability – Woody Higdon
First of all, debris flows are geological events similar to rock avalanches and landslides. Water-soaked masses of soil and rock charge down barren mountainsides. As a result, they funnel into stream channels, grabbing objects in its path, and forming dense, muddy deposits in low lying areas. Furthermore, debris flows can happen quickly and at great speeds. Ultimately, they can be very destructive.
Earth Systems participated as a sponsor. The seminar moderator was Darrin Hasham, PG, CEG, Engineering Geologist at Earth Systems.
