Debris flow is a type of mass wasting event where a combination of loose materials such as soil, rock, and vegetation move rapidly downhill due to gravity. These events are typically triggered by heavy rainfall or snowmelt, which saturates the slope and causes the materials to become unstable and flow downhill in a destructive manner. Debris flows can be highly destructive and pose a significant risk to human lives, property, and infrastructure. Researchers study debris flows to better understand their triggers, behavior, and potential impacts in order to develop strategies for mitigating their effects and improving early warning systems.
