Abstract : This Coastal and Hydraulics Engineering Technical Note (CHETN) contains a description of the process used to generate a scale factor for a 1:30 physical model of the Burlington Northern Santa Fe Railway Company (BNSF) railway crossing on the Santa Ana River near Corona, CA. Data from the scale factor study provide an adjustment for applying documented scour behavior from round piers to a non-typical parallelogram tapered pier and proposed pier nose extension found at the BNSF Bridge. The scale factor establishes the worst-case scour depth for the current bridge configuration and the proposed pier nose extension.
