Beach profiles have been surveyed at monthly intervals between 1972 and 1988 at Moruya on the South Coast of New South Wales, Australia. Four profile sites have been used as a data set to provide an understanding of changes to beach volume, width, and shape. Moruya beach represents a moderately high energy, microtidal environment, which responds in a dramatic way to major storm events such as those experienced in the mid‐1970s. This study distinguishes between profile characteristics associated with such a period (erosion‐dominated or EDP) compared with periods when accretion dominated (ADP) accompanied by foredune expansion in both height and width.
