Title: Relationship Between Erodibility and Properties of Soils
Accession Number: 01707036
Record Type: Monograph
Record URL: Availability: Find a library where document is available Abstract: Analysis of the erodibility of geomaterials is important for the study of problems related to soil erosion such as bridge scour, embankment overtopping erosion, and stream stability. Erodibility is a relationship between the soil erosion rate and fluid velocity or hydraulic shear stress. Since different soils have different geotechnical properties, their erosion rates vary. Additionally, existing laboratory and field erosion soil tests yield varied results that make it difficult to achieve consistent and reliable estimates. This report provides state transportation geotechnical engineers, hydraulic engineers, structural engineers, and other practitioners with a detailed analysis and a searchable Microsoft® Excel spreadsheet, NCHRP-Erosion, that uses statistical techniques to relate geotechnical properties to soil erodibility. Downloadable from the TRB summary web page for this report, NCHRP-Erosion is 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.
