← GeographyWhich effect occurs as wave energy dissipates after breaching a natural barrier composed of sand and dunes?
A)Increased sediment accretion offshore✓
B)Reduced wave refraction magnitude
C)Intensified longshore current velocity
D)Decreased back-barrier salinity
💡 Explanation
Increased sediment accretion offshore occurs because the breaking waves experience reduced energy, causing sediment deposition through wave damping, rather than erosion. Therefore, sediment accumulates offshore, rather than increased current velocity or salinity changes.
