On the integrated modelling of coastal changes

This paper introduces a possible approach to integrated modelling of coastal change, focusing on coastal land use and cover change. Some of the mostimportant open issues in the context of integrated modelling of coastal change are introduced. The paper focuses on methdological aspects. Specific reference is made to Physiographic Unit Modelling as an approach to better handle spatial variability and ‘morphogenesis’, and as a way to focus on coastal change mechanisms instead of absolute coastal dynamics for achieving an important simplification of the problem. The application is briefly discussed with reference to a ‘minimal model’. The methodological structure introduced is considered particularly suitable to represent, according to a variable degree of simplification, the integrative dynamics between resources and uses of the resources.
