The Mark near Zevenbergen
The Mark is a river in Belgium and the Netherlands. It rises north of Turnhout, Belgium. It passes through Hoogstraten before crossing the border with the Netherlands. In the city centre of Breda it receives its main tributary Aa of Weerijs. Below Oudenbosch the Mark is known under the name Dintel. The Dintel flows into the Volkerak (part of the Rhine–Meuse–Scheldt delta) at Dintelsas. The Dintel and Mark are navigable for cargo ships up to 86 m length from Dintelsas to Breda.
