It is typically used in legal and environmental contexts to refer to the average level of high tide or water elevation over a specific period.
Example: "The property boundaries are defined by the average high water mark, ensuring that the land remains protected from flooding."
Alternatives: "mean high water" or "average tidal height".
In stable marshes with slow wetland loss rates, we found that marsh elevation averaged 1 cm above mean high water, 15 cm above mean water, and 32 cm above mean low water levels.
Eisakhani and Malakahmad (2009) have reported excessive nitrogen and phosphorus content exceeding the WHO recommended value in both average and high water flow in Cameron Highland river.
The factors responsible for rapid spread in Haiti include: long-standing water and sanitary inadequacies in Haiti; the further disruptions to water and sanitary systems imposed by the earthquake; above average rainfall; high water and ambient temperatures; and insufficient capacity of the government infrastructure to respond to the crisis.
Hence, we recommend using a 1-year moving average of high waters (or hourly records if these are available) to correct the original data sets for seasonal and long-term sea level changes.
The mean annual discharge is measured at 239,000 cubic feet (6,770 cubic metres) per second at Fort Simpson; the average monthly flow at high water during the summer May toOctoberer) is more than 365,000 cubic feet (10,340 cubic metres) per second, and this seems to derive equally from the Liard and upper Mackenzie.
A 67-year average of lake levels by month shows that high water occurs, on the average, in September for Lake Superior and in June for Lake Ontario.
The sandstone reservoirs are generally thin and poor quality with an average porosity of 16 18% and high water saturation (above 50%), and oil mobility from the pressure test along the borehole (RCI) is small (<10mD/Cp).
Furthermore, the available water resources per capita in China are naturally low (only one-quarter of the world average; [4]) and unevenly distributed, with high water scarcity in the dry northern parts of the country [5].
This law of measurement occurs because any extreme value (one far away from average) is more likely to be a high water point than a true extreme.
In recent years, Venice's acqua alta, or high water, has resulted in an average of 100 floods a year.
