Which outcome occurs when rapid groundwater extraction lowers the potentiometric surface in karst regions?

💡 Explanation

Increased loading leads to sinkhole formation, because the decreased hydraulic head reduces support from hydrostatic pressure; Pipe collapse occurs as sediment is winnowed, therefore overburden collapse becomes dominant, rather than stable hydrostatic support alone.
