A quick definition of mean lower low tide:
Mean lower low tide refers to the average level of the lowest tides over a fixed period of time. Tides are the rising and falling of seawater caused by the attraction of the sun and moon. Mean high tide is the average of all high tides over a period of time, while mean low tide is the average of all low tides. Neap tides are lower than average because they occur during the first or last quarter of the moon, and spring tides are higher than average because they occur during the new moon and full moon.
A more thorough explanation:
Mean lower low tide refers to the average of the lowest low tides over a fixed period of time. It is used to measure a shore's boundary and is an important factor in determining the depth of water for navigation and construction purposes.
- If the mean lower low tide of a beach is 2 feet, it means that during low tide, the water level will be at or below 2 feet on average.
- When planning to build a pier, engineers need to know the mean lower low tide to ensure that the pier is high enough above the water level to avoid damage during low tide.
These examples illustrate how mean lower low tide is an important measurement for coastal planning and construction. It helps ensure that structures are built at a safe height above the water level and that navigation routes are deep enough for boats to pass through.
