Particle Size Analysis for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2014-18

These data are supplemental rip-rap gradation data (Wolman Pebble Count) in text (.txt) format, collected during 2014-2018 field seasons for select bridges in the United States. These data were collected using a measuring tape to determine riprap gradation (D15, D50, D85, and D100) on in-place riprap at bridge piers and/or abutments at various locations in each study reach. They supplement the Geospatial Data for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016–18. For high-resolution sites, traditional multibeam surveys were conducted using methods described in Huizinga (2015).
