Medium tidal high water
The mean high tide ( MThw for short ) describes the mean high water level at a given tidal level. The MThw is usually given in relation to the normal height zero (NHN). On the German North Sea coast, for example, the stalls are at around sea level + 1 meter. The individual measured values can vary greatly depending on the spring and nip tide . Subtracting the mean low tidal water (MTnw for short) from the mean high tide results in the mean tidal range .
The height of the mean tidal high water particularly influences the ecology of coastal areas. Depending on whether a piece of land is above or below this water level, it can be viewed as a salt marsh , high sand or mudflat area .
