A river mouth is the part of a river where the river flows into another river, a lake, a reservoir, a sea, or an ocean.[citation needed]

Water motion[edit] The water from a river can enter the receiving body in a variety of different ways.[1] The motion of the river mainly depends on the relative density of the river compared to the receiving water and any ambient motion in the receiving water, such as tides or seiches.[citation needed] If the river water is denser than the surface of the receiving water, the river water will plunge below the surface at the plunge curve. The river water will then either form an underflow or an interflow within the lake.[citation needed] If the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.[citation needed] Alongside these advective transports, inflowing water will also diffuse.[citation needed] Landforms[edit] At the mouth of a river, the change in flow condition can cause the river to drop any sediment it is carrying. This sediment deposition can generate a variety of landforms, such as deltas, sand bars, spits, and tie channels.[2] Cultural influence[edit] Many places in England take their names from their positions at the mouths of rivers, such as Plymouth ( River
Plym), Sidmouth ( River
Sid), and Great Yarmouth ( River
Yare).[citation needed] See also[edit]
