Bed features in the estuary of the Schelde (Belgium)

Bed features in a section of the estuary of the Schelde, located between the confluence of the Schelde and the Rupel and the Belgian-Dutch frontier, are studies with an echo sounder. Large scale ripples, with heights between 0.3 m and 3.3 m occur. The ratio, ripple height : mean grain size diameter, varies between 1.5 x 10 3 and 3 x 10 4 . Mud layers occur downstream. Some irregular features (pits and humps) are due to human influence. The slopes of artificial dumped clay varies between 0,14 and 0,20, in agreement with underwater slopes in the Veerse Meer and the Oosterschelde (The Netherlands... Mehr ...
