12b. DISTRIBUTION CODE 



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.
