Post-wildfire Hazards and Mitigation Measures

On-Demand

Presented by: Dr. T. Andrew Earles, PhD, PE, PH, D.WRE; Marta Alvarez, PE, RCE & PLS; Blanca Hoffmeier

Level: Intermediate
Duration: 1 hour
Type of Course: On-Demand

Wildfires in Southern California at the end of 2024, shortly before the onset of the rainy season set the stage for significant runoff and erosion as atmospheric rivers track across the region over the remainder of the rainy season. In mid-February, a storm with rainfall intensities on the order of an inch per hour triggered debris flows in recently burned areas that affected downstream urban areas. This webinar will discuss post-fire hydrologic hazards including debris flow, flooding, erosion, and water quality. The presenters will also discuss mitigation measures that can be implemented to reduce risk and the importance of warnings and evacuation orders.
