Distinguishing between debris flows and floods from field evidence in . . . This is because debris flows can move much faster than floods in steep channel reaches and much slower than floods in low-gradient reaches In addition, debris-flow deposition may drastically alter channel geometry in reaches where slope-area surveys are applied
Emergency Assessment of Post-Fire Debris-Flow Hazards - USGS Debris-flow hazard maps and geospatial data are now available on the Post Wildfire Debris Flow Hazard Assessment Dashboard Wildfire can significantly alter the hydrologic response of a watershed to the extent that even modest rainstorms can produce dangerous flash floods and debris flows
What’s Worse Than a Flood? A Debris Flow What makes a debris flow distinct from ordinary flooding, and what unique challenges does it pose? While flood flows are dominated by water, debris flows are a slurry of a lot of things, including boulders They are typically half water and half sediment, and they are very energetic
Fact Sheets | U. S. Geological Survey - USGS. gov Three fatalities were attributed to a fast moving type of landslide called debris flow Landslides cause fatalities and property damage throughout the Nation To reduce the impact from hazardous landslides, the U S Geological Survey develops and uses real-time and near-real-time landslide monitoring systems

This is because debris flows can move much faster than floods in steep channel reaches and much slower than floods in low-gradient reaches In addition, debris-flow deposition may drastically alter channel geometry in reaches where slope-area surveys are applied
Mechanics of debris flows and debris-laden flash floods A combination of solid and fluid resistance typifies debris flows and debris-laden flash floods In these flows solid resistance commonly is concentrated at the fronts of advancing bores that may be heavily freighted with rocks and woody debris
