The collection of clear-water contraction and abutment scour data at selected bridge sites in the coastal plain and piedmont of South Carolina
Clear-water contraction and abutment scour data were collected at 128 bridge sites in South Carolina. In the sandy soils of the Coastal Plain, clear-water-scour data were collected at 63 sites (scour depths ranged from 0.4 to 7.2 meters.) In the clayey soils of the Piedmont, clear-water-scour data were collected at 47 sites (scour depths ranged from 0 to 1.4 meters.) In the sandy, clayey soils of the Piedmont, clear-water-scour data were collected at 18 sites (scour depths ranged from 0.9 to 5.5 meters.) The field data are to be compiled into a data base that will include bridge age; basin, soil and hydraulic characteristics; and theoretical scour data. The data are planned to be statistically analyzed for significant relations that may help explain and (or) predict maximum scour depths at bridges in South Carolina.
