After The Flames Webinar Series: Assessing Postfire Debris-Flow Hazards

Description

Presenter: Jason Kean, USGS Landslide Hazards Program Research Hydrologist

Parts of the western U.S., like southern California and Colorado, have a history of damaging debris flows after wildfire. Other regions are facing new postfire risks due to expanded wildfire activity. After a wildfire, emergency managers need rapid answers to the questions: Where in the burn area are debris flows likely? How much rain will it take to cause a problem? And how big will that problem be?

Using examples of recent postfire events, Jason will describe how the U.S. Geological Survey and its partners work to answer those questions. He will also discuss current research to improve debris-flow hazard assessments with new tools to answer questions: Where will debris flows travel? How long it will take the burn area to recover? And what are the risks to future fires?
