Note concerning the origin of Scheldt estuary bottom sediments (Belgium, The Netherlands)

The analyses of gravels, shells and foraminifera of bottom sediments in the Scheldt estuary reveal a correlation between these sediments and the substratum. This is particularly so for the foraminifera assemblages. The results indicate on the one hand an erosion of Tertiary and Quaternary deposits and, on the other hand, a prevailing downstream sediment transport between the river Rupel and Antwerp and an up- as a downstream sediment transport as well in the river Western-Scheldt.
