Slack tide or slack water is the short period in a body of tidal water when the water is completely unstressed, and there is no movement either way in the tidal stream. It occurs before the direction of the tidal stream reverses. [1] Slack water can be estimated using a tidal atlas or the tidal diamond information on a nautical chart. [2]
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. The moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is ...
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
The maximum displacement of the amphidrome from the centre coincides with spring tides, whereas the minimum occurs at neaps. During spring tides, more energy is absorbed from the tidal wave compared to neap tides. As a result, the reflection coefficient α is smaller and the displacement of the amphidromic point from the centre is larger.

“Those wind-driven waves occur on top of the tides and any effect from the coastal Kelvin waves.” High surf sent waves all the way up the beach in Cayucos, flooding the playground and nearby ...
A rip tide, or riptide, is a strong offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide. It is a strong tidal flow of water within estuaries and other enclosed tidal areas. The riptides become the strongest where ...
The high tides are predicted to happen at South Florida’s coastline starting Tuesday morning, the city of Fort Lauderdale alerted. King tides might cause more flooding in Fort Lauderdale. Here ...
