Tidal flats, also known as mudflats, are flooded at high tide and exposed at low tide. ![]() Mudflats (tidal flats) are areas in which coastline shores are separated from the destructive forces of the ocean’s waves. In addition, the strong bidirectional currents, daily drying out, exposure to the elements, and abundant life create abundant indicators of these environments . These areas often have smaller particles than a normal shoreline since the tidal currents can pull marine sediments into the area. Shorelines that have strong tidal currents as well as seafloors with low gradients can have large areas that are submerged during high tide and exposed to air during low tide. Tides are currents that are the result of the gravitational forces exerted by the moon and the rotation of the earth. Shorelines that are influenced by strong daily tidal currents are called tidal mudflat depositional environments. For more information on Tides and Shallow Subtidal Environments, see this page. ![]() These are tidal currents. The tidal range of a particular location is dependent less on it position north/south of the equator than on other physical factors in the area topography, water depth, shoreline configuration, size of the ocean basin, and others . The vertical rise and fall of the tides, created by the gravitational force of the Moon and Sun acting on the oceans water, also creates a horizontal motion of the water in the bays, harbors and estuaries.
