Limited long-term (decadal) beach-nearshore profile observations suggest that during fairweather conditions, the beach-nearshore slope gradually steepens while the shoreline remains relatively stable. The steepening process is terminated by an extreme storm event during which sand is carried offshore, the shoreline migrates landward and the beach-nearshore slope flattens. When the interval between storms is large, the profile approaches a maximum steepness and its susceptibility to erosion and shoreline recession is maximized. A fair weather/storm model was developed to test the concept. Results show that the model may be a useful conceptual tool to examine medium- to long-term (years to many decades) beach-nearshore profile behavior. -from Authors
