A river is a natural freshwater stream that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river ...
A definition given by the state of Montana agrees, stating that a river source is never a confluence but is "in a location that is the farthest, along water miles, from where that river ends." [3] Under this definition, neither a lake (excepting lakes with no inflows) nor a confluence of tributaries can be a true river source, though both often ...
A confluence can occur in several configurations: at the point where a tributary joins a larger river ; or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers, forming the Ohio River); or where two separated channels of a river (forming a river island) rejoin at ...
River mouth of the Júcar, Cullera. A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. [1] At the river mouth, sediments are often deposited due to the slowing of the current, reducing the carrying capacity of the water. [1]
The water basin of the Wabash River; the other rivers (not including the Ohio River) are tributaries of the Wabash River. The Vermillion River (and its forks) is a highlighted example of a tributary of the Wabash River. The Wabash River is also a tributary of the Ohio River, which in turn is a tributary of the Mississippi River.
A river delta is so named because the shape of the Nile Delta approximates the triangular uppercase Greek letter delta.The triangular shape of the Nile Delta was known to audiences of classical Athenian drama; the tragedy Prometheus Bound by Aeschylus refers to it as the "triangular Nilotic land", though not as a "delta".

The thalweg of a river. In geography, hydrography, and fluvial geomorphology, a thalweg or talweg (/ ˈ t ɑː l v ɛ ɡ /) is the line or curve of lowest elevation within a valley or watercourse. [1] Its vertical position in maps is the nadir (greatest depth, sounding) in the stream profile.
A riverscape [1] (also called river landscape) [2] comprises the features of the landscape which can be found on and along a river. Most features of riverscapes include natural landforms (such as meanders and oxbow lakes) but they can also include artificial landforms (such as man-made levees and river groynes). Riverscapes can be divided into ...
