Which outcome is MOST LIKELY when heavy rainfall exceeds natural levee infiltration capacity along a major river?

💡 Explanation

When rainfall exceeds infiltration, hydrostatic pressure increases because the levee's structural integrity becomes compromised, leading to overtopping and accelerated erosion. Therefore, accelerated levee erosion occurs, rather than groundwater recharge, debris flows, or sediment reduction, which rely on differing hydrological mechanisms.
