Description :
Three sonographs of a part of a subtidal channel, located in the Oosterschelde, are described, interpreted and used to determine the asymmetry of the bedforms. Current profiles and directions are used to explain differences in dimensions and characteristics of the bedforms. The relations between current velocity parameters and bedforms characteristics in intertidal zones do not apply to subtidal forms. The division in the depth-velocity diagrams between the types of 2d and 3d bedforms of Dahymple et al. (1978) is not valid.
