Which outcome occurs when housing development disrupts sediment supply to barrier islands?

💡 Explanation

Increased erosion of dunes occurs because reduced sediment replenishment bypasses natural coastal protection, the 'sediment budget'; therefore, frontal dunes degrade rather than migrating/expanding, which would require sediment input, and are unrelated salinity diffusion.
