A principal research objective in coastal geomorphology is to define trends of phenomena, be it sea level or shoreline change. Many coastal states are presently utilizing historical shoreline change data to predict erosional trends for use in establishing building setback lines. A major concern involves choosing the appropriate statistical technique for trend determination. Unfortunately, shoreline position data are very limited and irregularly spaced through time.
