| Abstract: | The ebb-tidal delta model of McBride and Moslow is the most comprehensive on the morphogenesis and distribution of shoreface ridges along the US Atlantic seaboard to date. This discussion evaluates the applicability of the above model to the southern North Sea barrier island coast. Results indicate that the characteristics of the North Sea shoreface-connected ridge sediments display a genetic relationship with those of the inlet ebb delta as implied by the ebb-tidal model. By contrast, ridge orientation is not well accounted for by lateral inlet migration and shoreline recession as suggested by the model. A possible reason for the aforementioned discrepancy is discussed. |
