Scour Evaluations of Two Bridge Sites in Alabama with Cohesive Soils

Curry et al. (2002) conducted a scour evaluation study on bridges in Alabama that had experienced significant flood events (100 year event or greater). It was reported that current methods developed for noncohesive soils described in HEC-18 (1995 Third Edition) were inadequate for computing scour in cohesive soils. This report provides further evaluations of scour at two sites in Alabama with cohesive soils using methods developed recently by Briaud et al. (1999, 2001a, 2001b, 2003) and Guven et al. (2002a, 2002b). Comparisons of calculated scour obtained with the new methods for cohesive soils indicate better agreement with field observations.
