Six yearly evaluation of the Scheldt estuary

13 November 2018

The Scheldt estuary comprises of the Sea-Scheldt and its freshwater tributaries in Belgium, the brackish to saline Western-Scheldt in the Netherlands and its mouth into the North-Sea. Thanks to its extent and the occurrence of a complete salinity gradient, the ecology enjoys international recognition and protection. The estuary also forms the source of several economic activities such as fishery, sand mining, tourism and of course the access to several major ports.

The Flemish-Dutch Scheldt-Committee

The interaction between humans and nature is not purely mutual-beneficial. The history of this area is characterised by large floods. Moreover, by the end of the 20th century, this waterbody was considered as one of the most polluted estuaries in Western-Europe. Every 6 years, the Flemish-Dutch Scheldt-Committee evaluates the changes in this transboundary area: what is the state of affairs concerning safety, accessibility of the ports and the environment? Is the system evolving in the right direction? What is the anthropogenic impact?

The role of Antea Group within the project

The consortium formed by HKV Lijn in Water, Bureau Waardenburg en Antea Group evaluated the period 2010-2015. The integrated approach comprised analyses of several pillars: from human activities and policy measures, over hydrodynamics and morphology, to water quality and ecology. Antea Group investigated the aspects morphology, dredging and water quality.
