Toward a qualified process for coastal models: Integrated Development of Applied Systems for Coastal Management (IDeASyCoM)

This paper describes a generalisation of the integrated design method for environmental modelling. The wide range of processes determining coastal morphodynamics and their temporal and spatial variability give rise to a large number of possible scenarios that can be addressed using modern sediment-transport models. The exhaustive assessment of detailed model functionalities is time and resource consuming because of a priori decision making. Methods to prioritise the functionalities to be addressed are necessary. The Integrated Development of Applied Systems for Coastal Management (IDeASyCoM®) based on a decision-support system has proven to be efficient for identifying coastal managersʹ needs and defining priorities as well as for handling and capitalising on existing knowledge.
