Which outcome increases down-drift when groynes trap sediment?

💡 Explanation

Increased coastal erosion occurs down-drift because sediment is trapped up-drift by groynes, resulting in sediment starvation; therefore erosion increases, rather than sediment accretion or stability which would build up geographical features.
