Français : Des berges lagunées ont été créées (2010) par VNF (Voies navigables de France), en guise de mesure compensatoire à la mise à grand gabarit de l'Escaut dans le nord de la France.
Le lagunage est structuré en méandres de manière à allonger l'écotone eau-sol et à épurer l'eau de l'Escaut. Il est alimenté par l'Escaut lui-même, passivement ou plus "activement" lors du passage de chaque péniche (qui produit une vague avec surpression puis dépression) English: Banks with subnatural lagoons (w:en:Constructed wetland) were created (2010) by VNF (Waterways of France), as a countervailable to set wide gauge of the Scheldt in the north of France, on the edge of the river.
The lagoon is divided into meanders in order to extend the ecotone soil-water and purifying water of the Scheldt. It is powered by the Scheldt itself passively or more "active" during the passage of boats (which produces a wave with pressure and depression). Nederlands: Banken met tuurlijk lagunes (helofytenfilter) zijn gemaakt (2010) door VNF (Waterwegen van Frankrijk), als een milieumaatregelen / compenserende om breedspoor van de Schelde in het noorden van Frankrijk, aan de rand van de rivier.
De lagune is verdeeld in meanders met het oog op uitbreiding van de "ecotone" grond-water en zuiveren van water van de Schelde. Het wordt aangedreven door de Schelde zelf passief of meer "actieve" tijdens het passeren van schepen (waarvan een golf produceert met druk en depressie). |
