Relationship Between Erodibility and Properties of Soils

NCHRP Report 915: Relationship between Erodibility and Properties of Soils—now published—provides state transportation geotechnical engineers, hydraulic engineers, structural engineers and other practitioners with a detailed analysis and a searchable spreadsheet that uses statistical techniques to relate geotechnical properties to soil erodibility. The appendices include a searchable database that includes compiled erosion data from the literature review and a plethora of erosion tests. It contains equations that may be used to estimate the erosion resistance of soil and determine whether erosion tests are needed. NCHRP-Erosion—a relational global erosion spreadsheet—allows the user to perform multiconditional inquiries between erodibility parameters and soil geotechnical properties. The following appendices to NCHRP Report 915 were published online in a single Appendices Report: Appendix 1: Erosion Test Results Spreadsheets, Appendix 2: Geotechnical Properties Spreadsheets, Appendix 3: First and Second Order Statistical Analyses Results, Appendix 4: Deterministic Frequentist Regression Analysis, and Appendix 5: Probabilistic Calibration Results.
