Methods for assessing channel conditions related to scour-critical conditions at bridges in Tennessee
B.A. Bryan, Andrew Simon, G.S. Outlaw, Randy Thomas
1995, Water-Resources Investigations Report 94-4229
The ability to assess quickly the potential for scour at a bridge site, to evaluate those bridges with the greatest potential for significant amounts of scour, and to then identify scour-critical structures is important for public protection and bridge maintenance planning. A bridge-scour assessment information form was developed for collecting...
