Which outcome occurs when excessive impermeable surfaces cover alluvial plains?

💡 Explanation

Increased impermeable surfaces prevent water infiltration, causing rapid surface runoff; therefore, `increased flash flood frequency downstream` results, because water accumulates quickly. This occurs rather than groundwater recharge, which requires permeable surfaces.
