Wildfires can dramatically alter how water moves across the landscape. As a result, even modest rainstorms can trigger dangerous flash floods and debris flows in steep burned areas. In response, the USGS produces postfire debris-flow hazard assessments for recently burned areas. These hazard assessments estimate the likelihood, volume, and combined hazard of debris-flows in recently burned. This...
Postfire debris-flow hazards
Wildfires can dramatically alter how water moves across the landscape. After a fire, vegetation is removed and soil properties change, reducing the ground’s ability to absorb rainfall. As a result, even modest rainstorms can trigger dangerous flash floods and debris flows in steep burned areas. Postfire debris flows are fast-moving mixtures of water, mud, rocks, and vegetation that can surge...
