Evaluation of Abutment-Scour Equations from NCHRP Projects 24-15(2) and 24-20 Using Field Data

The primary objective of this investigation is to test and evaluate the abutment-scour prediction methods developed in the National Cooperative Highway Research Program (NCHRP) Projects 24-15(2) and 24-20, using United States Geological Survey (USGS) field data. The USGS field data will include the 324 abutment-scour measurements collected in South Carolina (Benedict, 2003), Maine (Lombard and Hodgkins, 2008), and the USGS National Bridge Scour Database (NBSD; http://water.usgs.gov/osw/techniques/bs/BSDMS/index.html, accessed May 14, 2009; Wagner et al., 2006) summarized in table 1. Results from the analysis will identify performance characteristics for each scour-prediction method and will help formulate application guidance. The USGS abutment- and contraction-scour field data used to test the newly-developed NCHRP scour-prediction methods primarily represents scour associated with clear-water scour conditions. Therefore, findings in this investigation will be limited to this type of scour.
