Debris flows are rapid mass movements of saturated, unconsolidated debris such as soil, rock, and vegetation down steep slopes. They are commonly triggered by intense rainfall, snowmelt, or earthquakes, and can cause widespread erosion, destruction of infrastructure, and loss of life. Research in this area focuses on understanding the processes that control debris flow initiation, movement, and deposition, as well as developing predictive models and mitigation strategies to reduce the risks associated with these hazardous events. Additionally, research often investigates the impacts of climate change on the frequency and magnitude of debris flows in different regions around the world.
