The objective of this investigation is to verify the deficiencies that incorporate both modelled and measured suspended sediment concentrations (SSC) data in a tidal dominated area. For this purpose a tidal channel, in the North Sea, was considered as the case study. The profiles of SSC from a model were compared with those from the field, in which some dissimilarity was observed. Intensive investigations were carried out to detect that the most discrepancies occur in shallow parts of the area and also during the low velocities. The origin of the shortcomings in regard with the modelling and measuring technique are discussed.
