ABSTRACT
Intertidal depositional areas are predominantly flat, which reflects the sheet-wise movement of the water propagated by tides and waves. This also applies to the smaller intertidal areas such as the intertidal parts of largely subtidal deposits like the tidal deltas at inlets and the sand- or mud banks in tidal estuaries. All intertidal deposits, by definition, are located in tidal areas that are predominantly depositional. Usually, however, there is a mixture of local, regional, and temporal deposition alternating with erosion with an overall net sedimentation. Even in King Sound, where erosion seems to dominate, intertidal deposits are formed. E. J. Wright et al. and J. S. Pethick have indicated that the tidal flat and channel morphology and the energy of tides and waves are interrelated: the morphology depends on tides and wind, and the tidal properties and wave activity depend on the size and shape of channels and flats; any consideration of relationships has to take this interaction into account.
