CLASIFICATION OF COASTS
-
Emerged coast
Emerged coasts are a result of local tectonic uplift of the land surface or a fall in the elevation of sea level because of a reduction in the water volume of ocean basins.
A good example of an emerged coastline, because of its proximity to an active plate tectonic margin, is the west coast of North America.

Primary coasts
Are those that have been shaped by terrestrial agents (including those associated with plate tectonics as we know them today) and are subdivided into.
Secondary coasts
Those in which wave action and other coastal processes are the dominant control on the coast morphology and these are subdivided into wave erosion coasts, marine deposition coasts (barriers, salt marsh, etc.), and coasts built by organisms (coral coasts, mangrove coasts).

Erosional coasts
Exists where wave energy or ocean currents are very present, erosion of the coast will be the dominant mechanism of change. Are narrow and characterized by rocky shorelines exposed to high energy waves and supply relatively little sediment.

Classification based on wave-tide relation (Hayes, 1979)
According to Hayes, coasts can be:
-
-
-
Morphodynamic states of beaches (Wright, Short and Green, 1985)
-
According to authors, for wave-dominated beaches We can distinguish the next states
