Shoreline 

the line of intersection between the surface of a sea or lake and the surface of the land. It is the boundary of a given water basin. Since the level of large water basins changes even over short intervals of time, the concept of a shoreline is arbitrary; it is applied with respect to the average location of the water level over many years. Ancient shorelines, which are also encountered within the boundaries of a shore, were established by the extension of various ancient forms of coastal relief. The study of ancient shorelines provides material to clarify the history of the development of the shore and water basin as a whole; it also makes it possible to draw conclusions with respect to the nature and rates of vertical movements of the crust.
