Bridge Scour Explained

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.
