Tidevandscyklusser, also known as tidal cycles, refer to the regular and predictable changes in sea levels caused by the gravitational forces exerted by the Moon and the Sun, as well as the rotation of the Earth. These cycles are fundamental to coastal environments and have significant impacts on marine life, coastal ecosystems, and human activities.

The primary tidal cycle is the diurnal cycle, which occurs once a day and is characterized by a single high tide and a single low tide. This cycle is common in most coastal areas. In contrast, the semi-diurnal cycle features two high tides and two low tides each day, with the high tides being of approximately equal height. This cycle is more prevalent in areas with a continental shelf, such as the North Sea and the Gulf of Mexico.

The tidal range, the difference in height between high and low tide, varies significantly depending on the location and the specific tidal cycle. In some areas, the tidal range can be as small as a few centimeters, while in others, it can exceed several meters. The tidal range influences the type of coastal environment, with estuaries and tidal flats typically found in areas with a large tidal range.

Tidal cycles also play a crucial role in sediment transport and coastal erosion. The ebb and flow of tides can transport large amounts of sediment, shaping coastal landscapes over time. Additionally, tidal currents can erode coastlines, leading to the formation of cliffs, beaches, and other coastal features.

Understanding tidal cycles is essential for various applications, including navigation, coastal management, and marine conservation. By studying these cycles, scientists and coastal managers can better predict and mitigate the impacts of tides on coastal environments and human activities.
