The aim of the Rebecca project was to establish a connection between pressure and quality elements of the Water Framework Directive and to create tools to estimate the surface connection. The project was carried out in close co-operation with the GIG groups which led the calibration processes of the Water Framework Directive in the implementation process of the Directive.

The harbour of Esbjerg is situated in the Danish Wadden Sea of the North Sea that is characterised by high tidal variations with a high load of suspended sediments. This causes siltation of Esbjerg Harbour requiring yearly maintenance dredging of approximately 460,000 m³ of which 40,000 m³ is too contaminated to be dumped into the Wadden Sea. The harbour has proposed that a confined disposal site with an area of 26 hectare and a volume of 520,000 m³ should be constructed at the shallow part of the Wadden Sea in the harbour area. This site will have a capacity for about 20 years of disposal. The surplus water will be discharged to the sea. DHI is preparing an EIA and an application for the environmental license for the project. A mathematical model has been set-up concerning discharge of contaminants (heavy metals, antifouling agents and organic pollutants like PAH) from the disposal site. It includes a physical model describing the dispersal of pollutants from all pollution sources in the area so that the impact on the environment from all sources can be assessed. Based on the model an ecotoxicological assessment of the impact from the present situation and with the impacts from the discharge from the confined disposal site has been carried out.
