My thoughts are: Land is to River as Body is to Artery or veins~ perhaps?
The new land formed at the mouth of a river due to the deposition of soil is called a delta. Deltas typically form where a river meets a body of water, such as an ocean or lake, and the flow of the river slows down, causing sediments to settle. This process creates fertile land that can support diverse ecosystems and agriculture.
The land beside a river is called a riverbank. It is the area along the edge of the river where the water meets the land.

It is a river.
The floodplain is an area of flat land found on either side of a river that usually becomes wider as the river nears its mouth. A low watery formation of land at the mouth of a river is called a delta.

An area of land that drains to one river (or a river and its tributaries) is a drainage basin or watershed.
Deposition and erosion are two major processes by which a river changes the land. Erosion is the combination of weathering and deposition in which the water loosens and moves the land to another place.
It's called the land between the Tigris and EuphratesRiver and that is Mesopotamia
A river basin is an area of land drained by a river and its tributaries.
