    Dredged Sediments, Web-GIS and Analysis Tools – The CEAMaS case study
    (EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Cervera, David Roig; Sutton, Gerry; Wheeler, Andy; Masson, Eric; Lahlou, Dounia
    Spatial analytical techniques are commonly used to inform critical aspects of dredging operations, providing powerful decision-making capacity when used with appropriate datasets. Geographical Information Systems (GIS) provide an operational framework within which a variety of dredging- relevant geospatial tools can be implemented. These may be generic or specific to particular dredging operations, in the latter case producing data for large numbers of relatively discrete dredging zones or operations. Pooling and cataloguing these individual operations can create a rich set of resources (data and tools) of value to decision makers, not only for use in managing dredging operations but also, to support the potential reuse of the material and the treatment needed for the use of the dredged material (DM). Web-based GIS are an ideal medium for displaying inputs required to complete spatial analyses, providing decision makers with an easy-access tool for use in combining information to optimise decisions. The early adoption of web-GIS technologies during the initial planning phase of a dredging process can lead to improved outcomes. Not only are end-users furnished with a more comprehensive view of the spatial aspects of a project but actual rates of sediment re-use may be increased through the provision of access to efficient tools with which to readily examine a selected set of high potential re-use options.

    Marine sediment re-use in the ports of North Western Europe. Toward a spatial decision support system for “Civil Engineering Application for Marine Sediments” (CEAMaS project)
    (EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Masson, Eric; Lahlou, Dounia; Blanpain, Olivier; Chevalier, Guillaume; Debuigne, Tristan; Roig, David; Sutton, Gerry
    This contribution aims at presenting a spatial decision support system, in a geographical information system and applied to the assessment and the feasibility of a potential reuse path for marine sediments. Its objective is to compare different ways of adding value to sediment. A geographical information system allows a solution to be spatially analyzed, and was therefore chosen for our study. Then, in a geographical information system, a decision support system was developed and tested. This decision support system is based on a spatial dataset, which considers the places of dredging, the sites of treatment and adding-value, and the sites of reuse. Developments and results, funded by the CEAMaS Interreg IVB North Western Europe project, are presented in this contribution on which to build future analyses.
