Emergency Assessment of Post-Wildfire Debris-Flow Hazards
We conduct post-fire debris-flow hazard assessments for select fires in the Western U.S. We use geospatial data related to basin morphometry, burn severity, soil properties, and rainfall characteristics to estimate the probability and volume of debris flows that may occur in response to a design storm.

Debris-Flow and Flooding Deposits in Coastal Venezuela Associated with the Storm of December 14–16, 1999
By Gerald F. Wieczorek, Matthew C. Larsen, L. Scott Eaton, Benjamin A. Morgan, and J. Luke Blair
Heavy rainfall from the storm of December 14–16, 1999, triggered thousands of shallow landslides on steep slopes of the Sierra de Avila north of Caracas, Venezuela, and caused flooding and massive debris flows in the channels of major drainages that severely damaged coastal communities.
