In this work, we analyze morphological evolution and changes of the channel-shoal system in the Changjiang Estuary, a river- and tide-controlled coastal plain estuary, based on bathymetric data. Our model system is the Oosterschelde and Westerschelde because of (1) the different development of the tidal flats in both systems, (2) the long term data sets available from ecological and. 2 Tidal dynamics 23 Introduction 23 Equations of motion 24 Tidal response – localised 26 Tidal response – whole estuary 31 Linearisation of the quadratic friction term 38 Higher harmonics and residuals 40 Surge–tide interactions 44 Summary of results and guidelines for application 46 References 48 3 Currents The morphology of the Westerschelde displays a regular repetitive pattern that consists of mutually evasive meandering ebb channels and straight flood channels. These main channels are separated by sub and intertidal shoals and linked by connecting channels.

Royal Geographical Society nr. of estuary comprising all the morphological components in which we are interested: channels, islands, and intertidal ar-eas. The characteristic length scale is somehow related to the width of the estuary. Channels, islands, and intertidal areas can be separately studied at the mesoscale level, whereas the. Important morphological elements within each basin are channels, shoals and mudflats and marshlands in the back. Typical channel networks in such basins are like the branches of an apple tree (Van Veen), i.e. with higher-order bifurcations (Fig. 2).There is a significant long-term interaction between the morphology of the basin, the ebb-tidal delta and the adjacent coastlines: they form a. Gomso Bay point bars are well developed in the sinuous tidal channels (Fig. ). The channels are ebb dominated, which is evident in the overall channel morphology such as downstream or seaward-skewed meander bend. Small-scale bedforms, such as asymmetric 2D ripples, cover the surface of the upper part of the point bar (Fig. B and C).

In the Westerschelde, where the tidal flow is the major driving force for the morphological development, it may even control the sediment exchange between the ebb tidal delta and the estuary, as well as between the various parts of the estuary. The interaction between the morphology and the tidal asymmetry is schematically depicted in Fig. 2.   Observations on the changes of the large-scale morphology and tidal asymmetry in the Westerschelde estuary were used to evaluate the applicability of existing relationships between estuarine morphology and the asymmetry of the vertical tide. The results of the analyses show that shallow parts tend to be more flood-dominant than deeper areas.
