Scour Protection at Bridge Piers (BD 97/12)

This standard details the requirements for protecting bridge foundations from erosion caused by flowing water.

BD 97/12 provides guidance on the design and implementation of scour protection measures around bridge piers and abutments. Scour, the erosion of riverbed material, can undermine bridge foundations, leading to structural instability. The standard specifies methods for assessing scour risk and selecting appropriate countermeasures such as riprap or gabions.
