Ontwatering van slib is met de gangbare technieken tijdrovend, energieslurpend en milieuvervuilend. Er bestaat een natuurlijke manier om de waterfractie te verwijderen: met oli-gochaeten, wormen die zich voeden met restmateriaal, zoals de vertrouwde regen-worm. Maar het is wel nodig de omstandigheden te opti-maliseren, opdat ze hun nuttig werk kunnen doen.@en

The Ems and Loire evolved into hyper-turbid estuaries in the course of the 20th century. Winterwerp et al. (2013 a, b) argued that narrowing and deepening of these rivers induced a regime shift towards these hyper-turbid conditions. This regime shift was presumed to be driven by a positive feed-back between tidal amplification, tidal asymmetry and sediment-induced drag reduction. As also the Sea Scheldt was/is subject to narrowing and deepening, Winterwerp et al. reasoned that also this river may be at risk to become hyper-turbid.@en
