Pier and contraction scour in cohesive soils.

This report discusses the findings of a research project undertaken to investigate bridge scour in cohesive soils. The report presents a recommended method for predicting the extent of complex pier and contraction scour in cohesive soils. This report will be of immediate interest to engineers with responsibility for predicting the extent of scour at bridge foundations and to engineers with responsibility for designing bridge foundations and bridge scour countermeasures.
