Small streams flow into rivers and the rivers flow to bigger rivers.
The Great Basin Desert primarily is found in Nevada, Utah and California with small parts entering a few other states.
The Murray River and the Darling River are two completely separate rivers in Australia. Together, they make up the Murray-Darling Basin, from which much of southeastern Australia derives its water supply. There is no other name for these rivers.
It is the longest in the world.
Most of Lake Mead and the Great Basin are located in the state of Nevada. But part of Lake Mead is also in northwestern Arizona (behind the Hoover Dam) and the Great Basin technically includes parts of the other four states (Oregon, California, Idaho, and Utah) that border Nevada.
Much of the foods that they ate were vegetables, but they also fished in the rivers, and hunted rabbits, antelope, and sometimes buffalo. The desert land was not suitable for farming, so they mainly gathered Piñon nuts. The nuts were essential to the tribes of this area because they were an excellent source of protein, and could be stored over the winter, when food and other resources were scarce. These could also be ground up to make flour; which was helpful for making other foods. Lastly, they also fished for salmon and trout, which thrived in the rivers of the Great Basin, and were a staple in the natives' food supply.
bigger water basin
It went over smaller rivers such as at Jiumenkou. See photos at great wall forumIt went up to the edge of larger rivers and stopped there, continuing on the other side.
A river basin is any area of land that drains into a river system. The Amazon Basin is one specific river basin, namely all the land that drains into the Amazon River system (meaning: including all the streams and creeks that in turn flow into the Amazon.)
It is actually called the Murray-Darling basin, because it is fed by Australia's two largest rivers, the Murray and the Darling. The Murray-Darling basin is a geographical area covering most of the southeastern quadrant of the continent, fed by dozens of tributaries into the Murray River and the Darling River. Because it is well irrigated by the many rivers, it is also Australia's largest agricultural region, covering two full states and parts of two other states.
In Earth science, "divide" refers to a ridgeline or elevated feature that separates the direction in which surface water flows. It marks the boundary between drainage basins or watersheds, where water flows on one side of the divide will drain to one basin, and water on the other side will drain to a different basin.
they both had differennt rivers and both had different pharoahs and mesepotamia didnt have natural barriers like Egypt does
If the answer you are looking for is not "water" then I don't know of any other answer which would be specific to the rovers you have in mind, which you don't state. Which 5 great rivers - the world's, Asia's, America's.... ?
