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 from a river can enter the receiving body in a variety of ...
The outlets mouth of a river can take several forms. Tidal rivers (often part of an estuary ) have their levels rise and fall with the tide . [ 3 ] Since the levels of these rivers are often already at or near sea level, the flow of alluvium and the brackish water that flows in these rivers may be either upriver or downriver depending on the ...
Moreover, river mouth bars are important hydrocarbon reservoirs, [14] [15] and have been widely interpreted in the geologic record. [16] [17] Analyses of the hydraulic and sedimentologic conditions of river mouth bar formation, progradation and aggradation, and prediction on their shape, size and spacing are incredibly valuable for reservoir ...
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 ...
Inverness (mouth of the river Ness) Eyemouth (mouth of the river Eye) Since these names refer to rivermouths (or towns built on rivermouths), the elements aber and inver are the generic elements, whereas the other element (typically the name of the river) is the specific element, telling us which rivermouth is meant.
A mouth bar is an elevated region of sediment typically found at a river delta which is located at the mouth of a river where the river flows out to the ocean. Sediment is transported by the river and deposited, mid channel, at the mouth of the river.
At the mouth of a river, the change in flow conditions 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. Landforms at the river mouth drastically alter the geomorphology and ecosystem.

Drowned river valleys are also known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and the topography of the estuary remains similar to that of a river valley. This is the most common type of estuary in temperate climates.
