Starting from a six-year morpho-dynamic database, Wright and Short (1984) proposed a three-dimensional model incorporating quantitative parameters (height of breaker, speed of falling of sediment, wave period and slope of beach) and nominal variables relating to the associations of process and form (presence or absence of mud and its type), developing a classification of beaches in three states: dissipative, intermediate and reflective.Thanks to this classification, there are various applications both in the management of safety on beaches, planning health resources, and the dynamic behaviour, response and effectiveness of regeneration projects, etc.
