Geomorphology (from Ancient Greek: , “earth”;  morphḗ, “form”; and lógos, “study”) is the scientific study of the origin and evolution of topographic and bathymetric features created by processes operating at or near the Earth’s surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modelling.  Coastal geomorphology relates specifically to surface features that are, or have been, subject to coastal processes (driven by wind, waves, tides and associated currents). Sea-level change at time scales up to thousands of years that are associated with climatic and/or tectonic change may extend the effeted region significant distances beyond the current shoreline, as may the migration of sand dunes and the existance of inlets
