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).

Shorline armoring

This data set contains vector lines and polygons representing the shoreline within estuary catchments that have armored. These data are derived from the Environmental Sensitivity Index (ESI) classification system. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

Site Information for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016-18

These data are supplemental site information in portable document format (.pdf) collected during 2016-2018 field seasons for select bridges in the United States (Dudunake and others, 2018). These files describe building plans for countermeasures, a field from to describe conditions during site assessment, and a photo summary of the study area.
