MEAN HIGHER HIGH WATER Meaning and
Definition
-
Mean higher high water (MHHW) refers to a tidal datum that represents the average height of the highest tidal waters observed during a specific time period. It is typically calculated over a 19-year period known as the Metonic cycle, which is a common technique used to consider the varying astronomical factors affecting tides.
MHHW serves as a benchmark to understand and predict tidal events accurately. It is measured by taking multiple high tide observations over the specified period and calculating the average height of the highest tides recorded during that span. This calculation accounts for tidal variations and helps establish a reference level for the highest tide that can be expected at a particular location.
MHHW is essential for a multitude of coastal activities and infrastructure considerations. It aids in determining safe water depths for ship navigation, especially in shallow areas or navigational channels. It plays a crucial role in coastal engineering projects, such as designing breakwaters, seawalls, or other structures meant to protect coastal areas from storm surges. It also assists in shoreline management, beach replenishment projects, and studying the effects of climate change and sea-level rise on coastal regions.
By using MHHW as a reference, scientists, engineers, and coastal managers can make informed decisions and plan accordingly to mitigate risks associated with high tides and tidal events. Therefore, understanding the concept and application of mean higher high water is crucial for effective coastal management and the sustainable development of coastal regions.
