Holocene water level movements in the lower Scheldt perimarine area
Kiden, P. (1989). Holocene water level movements in the lower Scheldt perimarine area, in: Baeteman, C. (Ed.) Quaternary sea-level investigations from Belgium: a contribution to IGCP Project 200. Professional Paper. Geological Survey of Belgium, 1989/6(241): pp. 1-19
Gradient lines and local water level movements in the lower Scheldt river could be reconstructed on the basis of a number of newly collected radiocarbon datings. Due to the presence of a floodbasin effect in the lower Scheldt river region, local MHW level in the Belgian part of the river was situated below coastal MHW since about 4500 BP. This floodbasin effect controlled the rise of local MHW level up to 500 to 1000 AD. Since then, a marked decrease of the floodbasin effect caused a rapid rise of local MHW level and tidal amplitude along a large part of the lower Scheldt river on Belgian territory. The data also indicate that differential tectonic subsidence of the western and northern Netherlands with respect to the lower Scheldt area can not have been greater than about 1.6 cm/century over the last 5000 years.
