The average ELEVATION of all high waters recorded at a particular point or station over a considerable period of time, usually 19 years. For shorter periods of observation, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. All high water heights are included in the average where the type of tide is either semidiurnal or mixed. Only the higher high water heights are included in the average where the type of tide is DIURNAL. So determined, MEAN HIGH WATER in the latter case is the same as MEAN HIGHER HIGH WATER.
A tidal datum. The average of all the high water heights observed over the National Tidal Datum Epoch. For stations with shorter series, simultaneous observational comparisons are made with a control tide station in order to derive the equivalent datum of the National Tidal Datum Epoch.
Highest average level water reaches on an outgoing tide.
the average height of the high tides over a 19-year period. For shorter periods of observation,“mean high water†means the average height of the high waters after corrections are applied to eliminate known variations and to reduce the result to the equivalent of a mean 19-year value.
A tidal datum. The arithmetic mean of the high water heights observed over a specific 19-year Metonic cycle (the National Tidal Datum Epoch).” Proposed work and structures seaward of the mean high water line are subject to federal regulatory authorities carried out by the U.S. Army Corps of Engineers as well as State regulatory authorities. All land and water areas seaward of the mean high water line are subject to the Public Trust Doctrine and held in trust by the State of Connecticut for public use. The mean high water line also marks the seaward boundary of the jurisdiction of the Middletown Planning and Zoning Commission.
Mean High Water. In San Francisco Bay, there are two high tides each day, usually with different elevations. Mean High Water is defined as the average height of both of these two tides.
Tidal datum that is the arithmetic mean of the high water heights observed over a specific 19-year Metonic cycle (National Tidal Datum Epoch). For stations with shorter series, simultaneous observations are made with a primary control tide station to derive the equivalent of a 19-year value. Use of "mean high tide" is discouraged.
the average level of high tide for any area.
(abbreviated MHW). The average height of all the high water s recorded over a 19-year period, or a computed equivalent period.
highly debated line along the river that paddlers need to stay below. To be on the safe side stay down by the water except on property Canoe Outpost owns. Usually the mean high water mark is about 2 feet above normal water level so don’t go hiking around in people’s yards and pastures.
A tidal datum. The lower of the two high water levels in a tidal cycle. visual
The average level of all high waters at a place over a 19 year period.
