Which risk increases when wave energy encounters unconsolidated coastal sediment?

💡 Explanation

Increased wave energy destabilizes coastal sediments, increasing sediment transportation via longshore drift because wave action leads to higher erosion rates by hydraulic action and abrasion. Therefore, sediment supply to the longshore current increases, rather than decreased wave refraction.
