The currents associated with the tides are called flood currents (incoming tide) and ebb currents (outgoing tide). Having reliable knowledge about the tides and tidal currents is important for navigating ships safely, and for engineering projects such as tidal and wave energy, as well as for planning trips to the seashore.

Currents. Currents put motion in the ocean! Tides involve water moving up and down; currents involve the movement of water back and forth. Currents are driven by several factors. Tides are one of these. Wind, the shape of the land, and even water temperature are other facts that drive currents.
The incoming tide along the coast and into the bays and estuaries is called a flood current; the outgoing tide is called an ebb current. The strongest flood and ebb currents usually occur before or near the time of the high and low tides.
28 de mar. de 2023 · Tides are another type of wave motion – a change in the ocean water level that typically reaches a high and low twice a day, about six hours apart (called a semi-diurnal tide). The change from low to high tide is called the "flood tide" or “flow”.
Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour).
27 de feb. de 2024 · Currents. Ocean currents are non-tidal movements of water, which may flow steadily at all depths in the oceans and may have both horizontal and vertical component; a surface current can only have a horizontal component. In rivers and estuaries, there is often a permanent current caused by the flow of river water.
