Which hydrological outcome is accelerated when overlying soil collapses into a sinkhole?

💡 Explanation

Increased groundwater recharge occurs because direct access is created to the aquifer. Infiltration bypasses the soil matrix, eliminating retention; therefore runoff decreases, depletion increases and evapotranspiration is largely unaffected, rather than the others.
