- Bridge scour depth is the vertical distance between scoured channel geometry and a measurement reference surface1. The total depth of scour is a combination of long-term bed elevation changes, contraction scour, and local scour at each individual pier and abutment2. The equilibrium scour depth is achieved when material is transported into the scour hole at the same rate at which it is transported out3. There are different types of formulas used to find out the scour depth4. River-bed scour is a major source of damage to bridge piers and bridge abutments5.

A scour depth measurement can have a wide range depending on the method used to establish the reference surface.www.usgs.gov/publications/reference-surfaces-brid…The total depth of scour is a combination of long-term bed elevation changes, contraction scour, and local scour at each individual pier and abutment. Once the scour is computed, the HEC-RAS software automatically plots the scour at the upstream bridge cross section.www.hec.usace.army.mil/confluence/rasdocs/ras1d…The equilibrium scour depth is achieved when material is transported into the scour hole at the same rate at which it is transported out. Typically the maximum equilibrium clear-water scour is about 10% larger than the equilibrium live-bed scour.en.wikipedia.org/wiki/Bridge_scourThere are different types of formulas with respect to different parameters are used to find out the scour depth. In US the most commonly used equation is the following one; d s = scour depth y= flow depth at upstream of the pier K 1,K 2,K 3 are pier nose shape correction factor, angle of flow attack, and bed condition respectively b= pier widthengineeringcivil.org/articles/bridge/scouring-in-brid…River-bed scour is a major source of damage to bridge piers and bridge abutments. When scour depth exceeds design limits, the supporting material around the footings is washed away and the structure becomes unstable. Equations for predicting scour-depth show a significant lack of agreement so portable equipment for measuring scour is needed.www.usgs.gov/publications/measurement-scour-de… - People also ask
