A low-head dam.
Sunlight warms the waters on the ocean surface. Some heat energy is transferred to cooler waters through convection.
As water is on top of the ocean, wind pushes it along, creating a current. As it warms, it interacts with lower colder waters, pulling them along with it. As water cools, it rises and this interaction creates ocean currents.

Equator due to the trade winds pushing the surface waters westward. This creates the Equatorial Counter Current, which flows eastward at the surface.
Ocean currents moving away from the equator bring warm waters.
Ocean currents.
waters of the ocean that move in giant streams are called currents.
Deep ocean currents and surface currents do meet, but mixing is limited. The waters stratify based on temperatures and salinity. The higher the salinity, the heavier the water.
Cyclones cannot hit Adelaide. Cyclones form in warm tropical waters, and then follow warm currents, but no warm currents extend from Australia's warmer waters to the south where Adelaide is located.
