Nearly 10,000 years ago, a Neolithic Engineer built the world's first tidal pathway near the Persian Gulf in Southern Mesopotamia. It was a little basic contradiction with only one moving piece. However, it was the development that made human development possible in the world as soon as possible. When socialism worked, human history was also spent a few minutes.
The tidal input is a water control device which allows water to move from one direction (between low tides) and in the opposite direction (between high tides and fluctuations). A large check valve. This restriction facilitates the digging and depletion of the ripple plain when connected to a pipe through a lever.
Mesopotamia is known to support human progress. This is where large-scale agricultural farming begins where a growing population and important urban areas emerge. Human development!
The development of a comprehensive flood-level diet is dangerous: a surge spreads everywhere and floods everything. Products to the starving people, starving to death and kicking the rules of mayhem. Fillers take care of this matter and do not need to be high as long as you are close to the stream that is regularly affected by the level of the eye.
How high can ripple water be? Answer: In addition to one or two, the most remarkable tide is as high. A dam at a foot height may be sufficient at the right place, which is generally close to a domestic waterway, with an extremely slight angle to the water level flowing here and there.
