Risk Assessment of Fuel Management Practices on Hillslope Erosion Processes (Phase I)

摘要

After wildfires, the use of rapid response field protocols allowed measurements of postfire soil infiltration, soil erodibility, and hillslope erosion rates, while long-term measurements provided data on postfire rehabilitation treatment effectiveness and general recovery rates. These data were used to expand and validate the current suite of web-based erosion prediction tools, and to develop a conceptually different erosion risk management tool, ERMiT. ERMiT's probabilistic analysis not only accounts for the variability in climate, soil properties, and spatial burn severity at the hillslope scale, but also provides the probabilistic output needed for postfire risk analysis. The custom interface is designed for use by hydrologists and soil scientists and is available to the public, along with our other erosion prediction tools, on the Internet.
