Currents
The water cycle, and Hydro-Kinesis, describes the movement of water. The process of water moving, both inside and out of pipes, is termed to be Flow. This also includes truck-hauling. The process of moving water is the cause of Erosion and rivulets and streams and little rivers like the Hay and the Berland. Rivers to the Oceans is definitely a separate aspect.

The water in the oceans come from the rivers!
Moving water is often referred to as a current. This term is used to describe the continuous flow of water in rivers, streams, and oceans caused by various factors such as tides, wind, and gravity.
