Which outcome occurs when levee construction obstructs sediment transport?

💡 Explanation

Increased coastal erosion occurs because interrupted sediment supply prevents natural beach nourishment; this is due to sediment starvation. Levee construction prevents overland flow; therefore sediment doesn't reach the coast, rather than increasing deposition due to reduced energy.
