Which risk increases along coastlines because longshore drift deposits sediment against an offshore barrier island?

💡 Explanation

Increased flooding occurs because **sediment accretion** narrows the channel between the barrier island and mainland, reducing the outflow of floodwaters; therefore, storm surge heights rise rather than salinity decreasing because the volume change is negligible.
