Streambed Stresses And Flow Around Bridge Piers

Scour of streambed material around bridge foundations by floodwaters is the leading cause of catastrophic bridge failure. This study defined streambed stresses around a full-scale bridge pier & compared that info. with streambed-stress data collected in the lab. on small-scale bridge piers. Both the magnitude & dist. of streambed stresses are compared for the full-scale & small-scale bridge piers. 2-dimensional velocity data were collected at 81 vertical locations around a cylindrical pier for 3 separate flow conditions. The velocity data was used to estimate streambed stresses. Contours of the stress data were produced for the full-scale bridge pier.
