Which outcome occurs when pressure imbalances shift groundwater flow paths?

💡 Explanation

Saltwater intrusion arises when lowered groundwater reduces hydraulic counter-pressure against seawater; the mechanism is hydraulic gradient reversal. This occurs because the saltwater flows into the aquifer rather than the freshwater flowing out to the sea.
