Scouring is the result of _______________.
AI Explanation
The correct answer is D) interruption of the normal current flow by the footing.
Scouring is the erosion of soil or rock around a structure's foundation caused by the disruption of normal water flow patterns. When a footing or other structure is placed in a waterway, it interrupts the normal current flow, which can lead to concentrated areas of high velocity flow and subsequent removal of soil material around the structure. This is known as scouring and can undermine the stability of the foundation if not properly addressed.
The other answer choices do not accurately describe the cause of scouring. Scouring is not directly related to mud-slide zones, rapid soil penetration, or the extraction of legs from high cohesion soils.
