What are the two types of river mouth?

As far as sea (marine) hydrological regimes are concerned, river mouth areas can be divided into: (1) tidal, and (2) non-tidal. River mouths are considered tidal when the tidal range is above 0.3 m.

Where is the mouth of the river?

The mouth of a river is where it meets: the sea, a lake or a larger waterway and ends its journey. Deposition often happens where a river channel enters the still water of a lake or the sea. If sediment is deposited faster than it is carried away, it builds up and forms a raised area called a delta.

Why is it called mouth of the river?

The place where a river enters a lake, larger river, or the ocean is called its mouth. As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water. The river mouth is where much of this gravel, sand, silt, and clay—called alluvium—is deposited.

The tributary that started the farthest distance from the river’s end would be considered the source, or headwaters.

What is the main part of the river called?

The start of a river is called the source or head water. The part of the river that is near the source is called a ‘young’ river. A young river is often in a V-shaped river bed, and flows quickly downhill over stones, and around big rocks. Young rivers often have lots of small waterfalls and rapids.
