Wildfires are increasing in size and severity across the western U.S. (Stephens, 2005; Littell and others, 2009). Concurrently, encroachment and development into the wildland-urban interface (WUI) is increasing, placing people at greater risks from wildfires and from the aftermath of fires (Stein and others, 2013). The Arizona Geological Survey (AZGS) is using data from recent wildfires and debris flows in Arizona, in cooperation with the U.S. Geological Survey (USGS), to assess how well available USGS models predict post-wildfire debris flows and to define rainfall intensity-duration thresholds that trigger post-fire debris flows. DI-44 version 1.0 contains the data collected and developed during the initial phase of this work. A short description of the project is provided below; a full description is in Appendix B of Youberg (2014). Included in this report are the geospatial data from the study: study basins and outlet locations, wildfire perimeters and final soil burn severity data, rain gauge locations, and 10 m digital elevation models with associated hill shaded models. Data from new wildfires will be added as they become available.
