Which outcome occurs when nearshore wave refraction diminishes along a coastline exhibiting longshore drift?

💡 Explanation

Decreased wave refraction reduces wave energy, which results in less sediment mobilization via longshore drift; therefore, sand supply decreases downdrift because sediment transport is impaired, rather than increasing deposition upgradient or affecting thermal stratification.
