"WebbTidal asymmetry develops during up-channel propagation into a shallow tidal basin. Pronounced tidal asymmetry (possibly leading to tidal bore formation) only occurs if during propagation a sufficiently large ratio is maintained. In many cases this condition is not met, because the tidal amplitude decreases during propagation. " - Tidal current asymmetry
