Which outcome is accelerated along coastal streams when increased storm surges occur?

💡 Explanation

Saltwater intrusion increases during surges because hydrodynamic dispersion mixes saline water inland; therefore aquifers become contaminated, rather than remaining unaffected, because the surge pressures overwhelm natural barriers.
