This report presents a coastal change case study and a subsequent coastal change application within a distributed architecture (DESIMNCOASTBASE approach). Firstly, cause-effect relationships between river output of suspended sediment, patterns in marine suspended sediment transport, and long-term coastal change were established.

The study of land-sea interactions showed:
-Seasonality in discharge of Total Suspended Matter (TSM).
-Seasonality in plume presence, extension and direction.
-Relationship discharge of TSM-plume presence, extension, direction.
-The impact of other factors possibly influencing the relationship.

The study of sea-coast interactions showed:
-Main cyclonic on-shore TSM transport direction.
-Location dependent trends in erosion or accretion.
-Relationship TSM transport direction-locations of erosion or accumulation.
-The impact of other factors possibly influencing the relationship.

Then, preliminary implementation in a Web mapping system (ArcIMS) was demonstrated in several figures (see cover page for an example). Towards the end of this report the scope expands from the specific case study to the requirements and possibilities for a generic operational system that can be used within the Marine Environment Unit. Here the focus is not on the technology needed to integrate data, but on locating data-sets. Finally, all these activities were placed in the overall frame of decision making in coastal management.
