The RUSLE erosion index as a proxy indicator for debris flow susceptibility

摘要: Debris flows represent dangerous occurrences in many parts of the world. Several disasters are documented due to this type fast-moving landslides; therefore, natural-hazard assessment debris is crucial for safety life and property. To aim, much current work being directed toward developing geotechnical-hydraulic models evaluation flow susceptibility. A common base such parameterization background predisposing triggering factors as inherent characteristics geo-materials, topography, landscape vegetation cover, rainfall regime, human activities, etc. which influence occurrence these processes on slopes. The same also taken into account soil erosion prediction models. Consequently, it seems worth investigating effectiveness index susceptibility indicator. a logistic regression analysis was carried out between assessed by means Revised Universal Soil Loss Equation (RUSLE) model inventory that have occurred an area Sicily (Southern Italy). Model assumptions were verified validated series statistical tools. Different possible scenarios evaluated considering hypothetical changes rate under different rain erosivity conditions. Notwithstanding rough approximations data collection, outcomes appear encouraging.
