The coastlines of the world's oceans encompass a tremendous variety of geomorphic and geologic structures. They range from rocky cliffs to sandy barrier beaches to low-lying swampy wetlands. The geomorphic forms were created by the interaction of antecedent geology, physical dynamic processes, and man- made intervention. Variable features are usually composed of unconsolidated materials that respond rapidly to changes in the dynamic environment. More stable features are usually associated with consolidated rock or occur in quiescent environments. The geologic history of shorelines can be inferred from a careful study of geomorphic structures, coupled with additional data on physical processes and historic events. Many of the study techniques are relatively simple, consisting of analysis of existing maps and historical sources. An understanding of the processes which have shaped the shore is crucial to the design of coastal structures and to the intelligent management of coastal resources and habitats. In addition, understanding of the form/process relationships between geomorphology and dynamics may allow coastal scientists to more accurately predict the results of construction or other modifications along the shore.
