Coasts provides a necessary background in geomorphology for those studying coastal systems. It describes the landforms that occur on the coast, their responses to the processes that shape them, and the pattern of evolution that can be determined for different types of coasts over thousands of years. Numerous examples from around the world illustrate the variety of environments. Particular attention is paid to coastal morphodynamics; the co-adjustment of process and form, on rocky, reef, sandy, deltaic-estuarine and muddy coasts.
