Post-fire debris flow research focuses on understanding the increased risk and likelihood of debris flows in areas that have experienced wildfires. Wildfires can destabilize slopes, increase runoff, and remove vegetation, making them more susceptible to debris flows during rainfall events. Research in this area seeks to predict, mitigate, and better prepare for post-fire debris flows to protect communities and infrastructure in fire-prone regions. This research typically involves studying the physical processes involved in post-fire debris flows, developing models to predict their occurrence, and implementing strategies to reduce their impact.
