Earth:Current (stream)

Short description: Flow of water in a stream caused by gravity

The water in this stream forms varying currents as it makes its way downhill

A current in a stream is the flow of water influenced by gravity as the water moves downhill to reduce its potential energy. The current varies spatially as well as temporally within the stream, dependent upon the flow volume of water, stream gradient, and channel geometry. In tidal zones, the current and streams may reverse on the flood tide before resuming on the ebb tide.
