Which phenomenon results when coastline shape alters wave-induced sediment transport?

💡 Explanation

Distinct coastline morphology obstructing wave directions sets up a difference in sediment movement; this is littoral drift divergence amplification because longshore currents are disrupted and forced to change direction rather than maintain constant equilibrium.
