Mhw mean high water
WebbLocally, we often refer to tides based on their height above the MLLW datum. The National Weather Service (NWS) defines tidal flooding for Charleston based on this datum, with flood stage beginning at 7.0-feet MLLW, moderate flood stage exceeding 7.50-feet MLLW, and major flood stage exceeding 8.0-feet MLLW. The intent of this map is to make it ...

WebbAbout Tides. The gravitational forces of the moon and sun create areas of high and low water on the earth's surface. As the earth rotates the location of high and low tide changes. The moon has the greatest effect on the water compared with the sun due to its proximity to the earth and the configuration of the sun and moon, whether aligned or ...

WebbMean Highest High Water is a reference surface corresponding to the height of high tides, averaged over a certain period of time (usually 19 years, a value close to a … The following tidal phases are commonly used in the definition of chart datums. Lowest astronomical tide (LAT) is defined as the lowest tide level which can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions. Many national charting agencies, including the United Kingdom Hydrographic Office and the Australian Hydrographic Service, use the LAT to define chart datums.
