Which risk increases when coastal afforestation near mobile dunes is conducted without permeability planning?

A)Exacerbated leeward dune migration
B)Enhanced offshore sediment transport
C)Increased stabilized dune erosion
D)Reduced longshore current deposition

💡 Explanation

When immobile trees are planted too densely, wind velocity increases through the barrier rather than being dispersed; this Amplified Wind Acceleration causes increased sand transport locally, because this concentrated area accelerates erosion; therefore, dune migration is exacerbated near the barrier, rather than decreased regionally.
