Coastal morphology is the study of the origin and evolution of coastal forms.
Coastal morphology or coastal geomorphology is the science of natural morphodynamic processes, which are responsible for shaping the coastal zone. The meaning of the Greek word "morphè" is form or shape. These natural processes, which involve wind, tides, currents, waves, biota, soil and sea-level changes, interact with the materials from which the coastal zone is built. Coastal zones around the world are shaped in highly diverse ways. The term coastal morphology is also used for the description of these very diverse coastal forms.
