Abstract: A mean water level in tidal bays and estuaries that is higher than the ocean mean water level (set-up) is a fairly common occurrence. Set-down of the mean water level can be shown to be possible by tidal asymmetry calculations and modification of Keulegan's Repletion analysis, but observations of the phenomenon are uncommon and ambiguous. Examination of hybrid model study results along with limited field data suggest that set-down does occur and may be influenced by engineering works.
