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.
High tide flooding describes coastal flooding conditions due to rising sea levels, sinking land, and the loss of natural barriers. Learn how climate change, strong tides, and prevailing winds can combine to create high tide flooding, and how it will become more frequent and severe over the next decades.
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 · Over the long term, recurrent high tide flooding causes more severe impacts, like damage to below-ground infrastructure and degraded wetlands. NOAA's high tide flooding information can help users plan for and mitigate impacts.
Learn how tides are caused by the moon and sun, and how they affect the water levels along the coastlines. See the animation of the flood and ebb currents, and the tidal range and currents in the open ocean and near estuaries.
28 de mar. de 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, sometimes referred to as nuisance flooding, sunny-day flooding, or king tide flooding, is occurring more frequently every year as sea levels continue to rise, and is increasingly disrupting coastal community life. 400 to 1,100% Increase.
