Which risk rises when groundwater flow increases where fractured limestone underlies epikarst?

💡 Explanation

Accelerated sinkhole formation results because increased flow enhances chemical weathering of widened solutional fractures via dissolution; therefore, that's the highest risk, rather than decreased aquifer recharge or slower mineral deposition because hydraulic capacity increases.
