Which coastline change results when seasonal river sediment load exceeds longshore drift capacity?

💡 Explanation

A delta forms because sediment deposition overwhelms the transport capacity of longshore drift, therefore, a river mouth delta grows larger to balance fluxes of eroded upland sediment rather than coastal features eroding from wave action or wind changes.
