Hydraulic Considerations for Shallow Abutment Foundations
This Technical Brief provides programmatic and technical considerations for evaluating and mitigating abutment scour at bridges with shallow foundations. The information supersedes certain materials on shallow foundations in two FHWA Hydraulic Engineering Circulars (HECs) “Evaluating Scour at Bridges” (HEC-18) and “Bridge Scour and Stream Instability Countermeasures” (HEC-23), and provides an improved pressure scour method for the document “Design and Construction Guideline for Geosynthetic Reinforced Soil Abutment and Integrated Bridge Systems.”
