[1] Sections of the river are under European protection as part of Natura 2000 "Scheldt and Durme estuary from the Dutch border to Ghent" (BE2300006).

The Zeeschelde derives its name from its susceptibility to the tides of the North Sea, causing a tidal wave to flow into the river twice a day.

A combination of spring tides, a northwest storm, and heavy rainfall can result in elevated water levels.

An exceptionally robust tidal wave surges into the Scheldt, obstructing the efficient drainage of rainwater and exerting pressure on the dikes.

Additionally, the inland basin of the Sea Scheldt progressively narrows, heightening the risk of dangerously high water levels.

Large amounts of silt are present in the silted-up area, which has caused quite a nuisance to residents and recreationists in the past.

[4]To increase the safety of the surrounding area and alleviate the gnat infestation, The Flemisch Waterway wants to carry out dredging works between Gentbrugge and Melle and implement the Sigmaproject Scheldemeander Gent-Wetteren.
