    The study area is situated between a cross-section positioned near Galgenweel (upstream of Antwerpen) and the Dutch-Belgian border. Previous determinations of the amount of mud were carried out in the same area (Bastin, 1993). The total quantity of mud was determined on the basis of data provided by the lithological map of the area of interest (Wartel et al., 2000). The data was collected by means of an acoustic survey which classified the sediments into five groups (mud, sandy mud, muddy sand, sand and hard bottom). For each bottom type a mud coefficient was determined, representing the percentage of mud present. In a first approach the sediment types were interpolated to a depth of -1 m, using a mean sediment density of 1.3 tons/m3 in the access channels and 1.45 tons/m3 in the main gully of the Schelde. The second approach, which took the thickness of the erosion sensitive layer for each sediment type into account, used specific densities for each sediment. The first approach yielded a total amount of 11.240.376 m3 of mud, representing a total amount of 7.572.585 tons of mud. The second calculation method produced a total amount of 5.245.756 tons of mud.
