Slow-moving Rivers

THE EDEN PROJECT CONTINUED:

Apropos of the Eden Project suggested in Installment 1 (Creation of a man-made riverbed across the Sahel of North Central Africa which would be fed by water from the Amazon River through deep-water pipelines across the Atlantic.): Imagine the number of jobs associated  with  such a huge project.  Think of the jobs that would be created in manufacturing, installing, and maintaining the deep water pipes which would be necessary for the twenty-seven-hundred mile pipe line across the Atlantic Ocean.  Think of the number of jobs that would be created to:  dredge the river bed; line the riverbed where necessary; house the workers;  provision the workers.  Think of the armies of workers, many of whom would stay on after the completion of the river to become citizens and found communities.  Think of the villages that would arise and attract services and the workers needed to provide the services.

Yes, the river project would probably take on some of the aspects of any boom economy.   But, for starters, the project would not have the more egregious negatives associated with boom economies engaged in the extraction of minerals.  No arsenic as is used in mining gold; no chemicals as used in “fracking” for oil in shale; no strip mining for coal.

Think of the new river as a permanent, flowing oasis.  As long as the Amazon keeps flowing, the new river would keep flowing, being the conduit for sustenance across a vast arid plane; providing environmental benefits for the African continent and for the entire global community; fighting desertification; combating global warming.

This huge project could be the start of renewal and growth for the entire world.   It could be a chance for peaceful international commitment to sustained growth and economic security for millions of the earth’s citizens.  Plus.  Think of the lessening of sea level rise by diverting water that would have gone into the Atlantic Ocean.

Imagine the water from one 6’ diameter pipe floated at half capacity, approximately 19,800 gallons per minute.  Imagine six tubes bound together in twos.  Approximately 118,800 gpm.    Imagine six bundles of six tubes.  Since the Amazon is as wide as it is (1 mile – 6.2 miles), and since the Amazon is as deep as it is (66 feet – 160 feet) ,  we could add many bundled tubes and provide for a man-made river the size of  the Pascagoula River in Mississippi, with a flow of 1000 cubic feet per second.  Or larger.

Worried that we might damage the integrity of the Amazon by siphoning off that much water?  The average flow of the Amazon River into the Atlantic Ocean is   4,200,000 cubic feet per second, an estimated seven times the discharge of the Mississippi River into the Gulf of Mexico.

THE EDEN PROJECT: To combat global warming and reverse desertification

How about transporting water, via large-diameter flexible tubing, from the mouth of the Amazon River (above the salinity line) across the Atlantic Ocean to a machine-excavated riverbed that would eventually traverse the African Sahel from Mauritania to the Red Sea.

Since flexible tubing (for deep water, suspended pipelines) and gigantic earth  movers (capable of moving more than 75,000 cubic meter of earth a day) are now viable tools, why not run  large-diameter flexible pipelines  from the mouth of the Amazon across the Atlantic Ocean to Mauritania to fill a man-made riverbed which would stretch across the Sahel (dry areas not yet desert) from the Mauritanian coast through Mauritania, Mali, Niger, Chad and Sudan which are all fighting desertification?

Couldn’t the flexible pipeline be floated deep enough below the ocean surface to avoid the surface problems of wind?  Couldn’t the pipeline be anchored to the ocean floor with cables to mitigate  the movement of the tubing by the ocean currents?

Couldn’t pumps capable of handling massive amounts of water, and powered by solar energy, be situated on the Mauritanian coast  to keep the river water flowing into the man-made (machine-excavated) river bed?

Why not create top soil by sowing successive plantings of fast growing vegetation irrigated by the new river so that the Sahel could provide sustainable agricultural economies in all countries through which the river runs?   Since trees are the most natural and efficient means of reducing carbon dioxide we have on the planet, why not plant trees along the river banks to begin reforestation in the Sahel?

No?  Can’t be done?  Too large a project?

Think of the Grand Canal in China, purportedly started  in the fifth century BC and finished  during the seventh century CE.  Eleven hundred miles long (or fourteen hundred miles long, depending on the Internet site visited) and constructed long before there was any harnessed  energy on the planet other than that of animals actually wearing harness.
