← GeographyWhich consequence results when coastal aquifers discharge excessively?
A)Salinity increases due to saltwater intrusion✓
B)Barrier island formation is accelerated
C)Wave refraction becomes less pronounce
D)Uplift reverses coastal land subsidence
💡 Explanation
Saltwater intrusion occurs because reduced freshwater discharge allows easier inland migration through the aquifer matrix. This is driven by hydraulic gradient changes associated to the Ghyben-Herzberg relation; therefore, saline water encroaches, rather than land rising or island accretion happening.
