This report presents a methodology for estimating the time rate of scour and the design scour depth for a bridge founded on rock. The report also includes design and construction guidelines for application of the methodology.
Reference: NCHRP Report 717, TRB
This report explores recommendations for a predictive equation for equilibrium local scour and a potential equation for predicting scour evolution rates at wide piers and skewed piers. The equations are designed to help provide better estimates of local scour ...
