Sea level is currently rising at 3.2 mm/yr, and scientists predict that global warming could cause a rise in sea level of 7 m if left unabated. The delivery of sediment from muddy rivers and streams keeps the coastal construction on the go. Despite the differences between submergent and emergent coasts, the effects of wave erosion and sediment deposition by currents cause them to share many features.
