The threats to coastal communities include extreme natural events such as hurricanes, coastal storms, tsunamis, and landslides, as well as longer-term risks of coastal erosion and sea level rise. The wave pattern created by this water movement causes a convergence of longshore drift on the opposite side of the island. A drowned river mouth indicates which of the following types of coastline?
