Bridge scour is the removal of sediment such as sand and
rocks from around bridge abutments or piers. Scour, caused
by swiftly moving water, can scoop out scour holes,
compromising the integrity of a structure.

Bridge scour is one of the three main causes of bridge
failure (the others being collision and overloading). It has
been estimated that 60% of all bridge failures result from
scour and other hydraulic-related causes

Scouring can be defined as a process due to which the particles of the soil or rock around the periphery of the abutment or pier of the highway bridge spanning over a water body, gets eroded and removed over a certain depth called scour depth.
Hydraulic Engineering Circular (HEC) has published a manual in which the methods are mentioned some of which are empirical equations or graphs to estimate the scour depth based on the discharge, flow velocity or flow depth etc.
