In
geomorphological studies, a wide range of coastal classifications based on
natural processes are available. These classifications results from very
different approaches but are not necessarily incompatible. Used criteria basically
include the tectonic and hydrodynamic controls, as well as the sedimentological response.
Hydrodynamics control includes classifications after wave parameters,
spring tidal range and a combination of both. A major advance in this type of
classifications was the inclusion of the term megatidal, previously applied in
ecological studies and later adopted in coastal geomorphology. Thus, Levoy et
al. defined as megatidal the coast with tidal ranges higher than 8 m, while
other authors agree to locate the limit of megatidal coasts at 6 m. Read more>>>>>>
