Tidal amplitude

The ETM is defined as a region where the SPM concentrations are considerably higher (10-100 times) than adjacent river or coastal end-members in estuaries. The location of the ETM is generally considered to be controlled by tidal amplitude, volume of river flow, and channel bathymetry.

Another surprising result is that the Tidal Amplitude can be negative. In other words, the shortest axis of the deformed body is aligned with the tide-raiser. This result may seem physically counter intuitive, but becomes more understandable if we consider the deformation of the planet throughout its interior. The solution (Appendix B) for the displacement at any location u(r, d) shows that the radial component of u, ur(r, ), at any given r has the same dependence on as the radial distortion of the surface ... 

Under exceptional circumstances, when the FBI has a very narrow vertical range and/or tidal amplitude is very small, it is possible to estimate the elevation of a former mean sea-level to +0.08 m (Antonioli et al. 1999), or +0.25 m (Lambeck 2002). However in most instances, FBIs occupy a comparatively wide interval within the intertidal zone and/or a large tidal range expands the vertical interval over which an FBI can survive. This commonly increases the uncertainty in relating a fossil FBI with a palaeo sea-level to a metre or more, usually sufficient to obscure any fine structure that might be present in a regional sea-level curve. 

The M2 tide propagates mainly from the Pacific into the SCS through the LS, and it is subsequently directed southwestward into the interior of the SCS and northward into the Taiwan shoal. The M2 tidal amplitude (about 0.2 m) is markedly diminished after passing through the LS from the Pacific (about 0.6 m), which is associated with strong tidal energy dissipation by the local topography.
