Bridge Scour Analysis Tools

Scour is the leading cause of bridge failure, and HEC-18 defines how to compute it. Listed here: HEC-RAS, which computes pier, abutment and contraction scour from its hydraulic results; SRH-2D, FHWA’s preferred 2D model for bridge hydraulics; and the FHWA Hydraulic Toolbox.
