It is a historic region of West Asia within the Tigris-Euphrates river system. In fact, the word Mesopotamia means “between rivers” in Greek. Home to the ancient civilizations of Sumer, Assyria, and Babylonia these peoples are credited with influencing mathematics and astronomy.
The civilization of Ancient Mesopotamia grew up along the banks of two great rivers, the Euphrates and the Tigris.
A tributary or affluent is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. A confluence, where two or more bodies of water meet together, usually refers to the joining of tributaries.
A tributary is a stream or a river which flows into a larger river. a tributary does not flow directly into a sea or ocean. For example, river Gomati and Son are the tributaries of river Ganga.
A tributary is a freshwater stream that feeds into a larger stream, river or other body of water. The larger, or parent, river is called the mainstem. 6 – 12+ Earth Science, Geography, Physical Geography.

A basin is a depression, or dip, in the Earth’s surface. Basins are shaped like bowls, with sides higher than the bottom. They can be oval or circular in shape, similar to a sink or tub you might have in your own bathroom. Some are filled with water.
A river basin is the portion of land drained by a river and its tributaries. It encompasses all of the land surface dissected and drained by many streams and creeks that flow downhill into one another, and eventually into the Milwaukee River.
Drainage basins are important in ecology. As water flows over the ground and along rivers it can pick up nutrients, sediment, and pollutants. With the water, they are transported towards the outlet of the basin, and can affect the ecological processes along the way as well as in the receiving water source.
Because water moves throughout a drainage basin either as surface or sub-surface flow to eventually form the network of channels which is the river system, any changes in land or water use within the basin are rapidly reflected in the river.
Everyone lives in a river basin, even if you don’t live near the water. The land that we live on eventually drains to a river or estuary or lake, and our actions on that land affect water quality and quantity far downstream.
River drainage basins A river basin or drainage basin is an area of land drained by a river and its tributaries . The edge of the drainage basin is known as the watershed .
Three zones are usually recognized – headwaters, where flow is usually lowest of any where along the system, slope is often steepest, and erosion is greater than sediment deposition; transfer zone, the middle range of the stream where slope usually flattens somewhat, more flow appears, and deposition and erosion are …
In geography, a confluence (also: conflux) occurs where two or more flowing bodies of water join together to form a single channel.
A continental divide is a boundary that separates a continent’s river systems. Each river system feeds into a distinct ocean, bay, or sea. The Loveland Pass, pictured here, is a continental divide in Colorado that separates water flowing into the Atlantic and Pacific ocean basins.
Most of the divide runs along the crest of the Rocky Mountains, through British Columbia and along the British Columbia–Alberta border in Canada, and through the states of Montana, Wyoming, Colorado, and New Mexico in the United States.
