Which outcome occurs when groundwater discharge is significantly reduced along a coastal barrier island?

💡 Explanation

Increased coastal erosion occurs on sandy coasts due to decreased discharge because freshwater normally helps cement & stabilize the dunes via mineral precipitation; therefore, less groundwater results in reduced cohesion, rather than the aquifer changes implied by the alternatives.
