Baïne
A baïne is a pool of water of a few dozen to several hundred metres in length, parallel to the beach and directly connected to the sea. Each one is spaced every 300 to 400 metres and formed under the influence of Water waves, waves and the tide. The French term ''baïne'' is typical for the Aquitaine coast of France in the departements of Gironde, Charente-Maritime and Landes (department), Landes, but it can occur on beaches throughout the world. When a wave hits the coast, it can pass over the sandbar that separates the ''baïne'' from the sea and enter it all along its length. When the wave subsequently recedes, the ''baïne'' water is pushed out through the single point where it was connected to the sea. At this point a rip current, a very strong offshore current, can occur. The current will vary depending on the height of the waves and the height of the tide. It is at its strongest and most dangerous during the final hours approaching low tide, and in the first hours afterwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Waves
In fluid dynamics, a wind wave, water wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result from the wind blowing over the water surface. The contact distance in the direction of the wind is known as the ''fetch''. Waves in the oceans can travel thousands of kilometers before reaching land. Wind waves on Earth range in size from small ripples, to waves over high, being limited by wind speed, duration, fetch, and water depth. When directly generated and affected by local wind, a wind wave system is called a wind sea. Wind waves will travel in a great circle route after being generated – curving slightly left in the southern hemisphere and slightly right in the northern hemisphere. After moving out of the area of fetch, wind waves are called '' swells'' and can travel thousands of kilometers. A noteworthy example of this is waves generated south of Tasmania during heavy winds that will travel across the Pacif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, 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"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquitaine
Aquitaine ( , , ; oc, Aquitània ; eu, Akitania; Poitevin-Saintongeais: ''Aguiéne''), archaic Guyenne or Guienne ( oc, Guiana), is a historical region of southwestern France and a former administrative region of the country. Since 1 January 2016 it has been part of the region of Nouvelle-Aquitaine. It is situated in the southwest corner of Metropolitan France, along the Atlantic Ocean and the Pyrenees mountain range on the border with Spain, and for most of its written history Bordeaux has been a vital port and administrative center. It is composed of the five departments of Dordogne, Lot-et-Garonne, Pyrénées-Atlantiques, Landes and Gironde. Gallia Aquitania was established by the Romans in ancient times and in the Middle Ages, Aquitaine was a kingdom and a duchy, whose boundaries fluctuated considerably.

Charente-Maritime
Charente-Maritime () is a department in the Nouvelle-Aquitaine region on the southwestern coast of France. Named after the river Charente, its prefecture is La Rochelle. As of 2019, it had a population of 651,358 with an area of 6,864 square kilometres (2,650 sq mi). History Previously a part of the provinces of Saintonge and Aunis, Charente-Inférieure was one of the 83 original departments created during the French Revolution on 4 March 1790. On 4 September 1941, during World War II, it was renamed as Charente-Maritime. When the department was first organised, the commune of Saintes was designated as the prefecture of the department (Saintes had previously been the capital of Saintonge). This changed in 1810 when Napoleon passed an imperial decree to move the prefecture to La Rochelle. During World War II, the department was invaded by the German Army and became part of occupied France. To provide defence against a possible beach landing by the Allies, the Organisation Tod ...

Rip Current
A rip current, often simply called a rip (or misleadingly a ''rip tide''), is a specific kind of water current that can occur near beaches with breaking waves. A rip is a strong, localized, and narrow current of water which moves directly away from the shore, cutting through the lines of breaking waves like a river running out to sea. The current in a rip is strongest and fastest next to the surface of the water. Rip currents can be hazardous to people in the water. Swimmers who are caught in a rip current and who do not understand what is happening, or who may not have the necessary water skills, may panic, or they may exhaust themselves by trying to swim directly against the flow of water. Because of these factors, rip currents are the leading cause of rescues by lifeguards at beaches, and in the United States, they are the cause of an average of 46 deaths by drowning per year. A rip current is not the same thing as undertow, although some people use the term incorrectly whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Height Of The Tide
Height is measure of vertical distance, either vertical extent (how "tall" something or someone is) or vertical position (how "high" a point is). For example, "The height of that building is 50 m" or "The height of an airplane in-flight is about 10,000 m". For example, "Christopher Columbus is 5 foot 2 inches in vertical height." When the term is used to describe vertical position (of, e.g., an airplane) from sea level, height is more often called ''altitude''. Furthermore, if the point is attached to the Earth (e.g., a mountain peak), then altitude (height above sea level) is called ''elevation''. In a two-dimensional Cartesian space, height is measured along the vertical axis (''y'') between a specific point and another that does not have the same ''y''-value. If both points happen to have the same ''y''-value, then their relative height is zero. In the case of three-dimensional space, height is measured along the vertical ''z'' axis, describing a distance from (or "above") ...
