In coastal oceanography, the terms ebb and flood refer to tidal currents. These terms are particularly relevant for tidal inlet systems: estuaries, tidal rivers and lagoons. The ebb current corresponds to seaward flow and the flood current to landward flow.
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range").
As the tide rises, water moves toward the shore. This is called a flood current. As the tide recedes, the waters move away from the shore. This is called an ebb current. The movement of water toward and away from the shore is illustrated by the movement of the green seaweed.
28. März 2023 · The change from low to high tide is called the "flood tide" or “flow”. The change from high to low tide is called the "ebb tide". Tides result from the pull of gravity from the Earth alone, between the Earth and the Moon, and between the Earth and the Sun.
High tide flooding falls into three levels of severity: minor, moderate, and major. The classifications measure how much water levels exceed average high tide for that location. Minor high tide flooding is when water levels reach 0.55 meters (1.8 feet) above average high tide.
3. Sept. 2014 · Ebb is the decreasing tide while flood tide is the increasing. The moment the tide changes is called slack water. There is 6 hours between each high and low. Tomorrow’s high tide will be about...
