| The Scheldt estuary is a vast ecosystem in which powerful natural forces prevail. Tidal action is a key element in the functioning of the estuary. The combination of tide and discharge results in a salinity gradient that is characterized by strong variations in the brackish part. The estuary is a highly turbidsystem. The load of suspended solids is determined by acomplex mix of factors. The dynamic interactions of the physicochemical and morphological parameters lead to a range of various habitats, with highly fluctuating conditions. This, together with the very heavy human impact, both morphological and chemical makes the estuary a very stressed environment in which the survival of plants and animals requires special adaptations. |

| The Scheldt estuary is exposed to large loads of carbon and nutrients. This leads to a eutrophication problem characterized by reduced oxygen concentrations and a huge efflux of CO<sub>2</sub>. In the coastal waters a degradation of the foodchain is noted caused by excessive nutrient supply. The capacity of the estuary to polish the water is important but can not cope with the vast scale of the immissions. Restoration and development of tidal wetlands can contribute in several ways to restore the water quality. Increase of water treatment is expected to have positive ecological results. Nevertheless, restoration of the oxygen conditions might counteract some purifying processes. |
