Definition: Bridge scour is the engineering term for the erosion of soil (sediment like sand, gravel) around a bridge's foundation, specifically piers and abutments. It's essentially the process of fast-moving water washing away the material supporting the bridge. This creates scour holes that can severely weaken the bridge's structural integrity and lead to collapse.

Definition Continue: The formulas you provided, stability factor = abutment width * soil bearing capacity and load factor = abutment width * abutment height * live load, are simplified and don't represent a complete abutment design. Abutment design is a complex process involving multiple factors and checks for various failure modes. These formulas seem to address only a very basic comparison of bearing capacity and applied load.
