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.
Sea level rises over several hours, covering the intertidal zone; flood tide. The water stops rising, reaching a local maximum called high tide. Sea level falls over several hours, revealing the intertidal zone; ebb tide. Oscillating currents produced by tides are known as tidal streams or tidal currents.
High tide flooding is when sea level rise combines with local factors to push water levels above the normal high tide mark. Learn how to classify and visualize high tide flooding, and how it affects coastal communities and infrastructure.
Find local water levels, tide and current predictions, and other oceanographic and meteorological conditions for your region. Access real-time and historical coastal flood information, high tide flooding outlooks, and coastal condition forecasts.
1 de ago. de 2019 · Learn about high tide flooding, the overflow of water that covers dry coastal land during high tides. Find out how to plan for and mitigate its impacts with NOAA's interactive products, outlooks, and data.
28 de mar. de 2023 · Learn how tides are caused by the gravitational pull of the Moon and the Sun, and how they vary depending on the position and orbit of these bodies. Find out what a flood tide is and how it relates to the change from low to high tide.
Flood tide is the rising part of the tide cycle, when water flows into a coastal area. Learn about flood tide, its opposite ebb tide, tidal force, tidal bore and more from Britannica's articles.
