Methodology of management of dredging operations I. Conceptual developments.
This article presents a new methodology for the management of dredging operations. Partly derived from existing methodologies (OECD, UNEP, AIPCN), its aim is to be more complete, by integrating the qualities and complementarities of former methodologies. Moreover, it was carried out in a context of sustainable development. Indeed, it supports, according to a framework of industrial ecology, the development and the implementation of solutions of waste improvement of dredged materials, in order to minimize the environmental impact of dredging. It also uses a tool of MultiCriteria Decision-Making Aid (M.C.D.M.A.), in order to integrate local characteristics. In addition, this tool, called DRAGSED, allows to a dialogue to be established between all the parties concerned with a dredging project (harbour's authorities, industrialists, municipalities, administrations, populations, associations,...). Thus, the implementation of this methodology enables consensus to be reached for the dredging solution retained. It also proposes an environmental follow-up, which will allow an evaluation during its application.
