What would happen if we flooded the Sahara desert?

“Floods, landslides most of the vegetation would die.” The land isn’t covered with vegetation, so the erosion will be immense. In large parts of the Sahara the aquifer isn’t far below the surface. With 300 inches a year, you have enough water to saturate 75 FEET of sand.

Can you pump water from the sea?

The Yokota Seawater Intake Pump provides suction of seawater from the sea at a distance of 400 meters. The ultimate method of solving water shortages in various countries is the use of the inexhaustible supply of seawater. In this respect, there is a growing trend for the use of seawater.

How long ago did the Sahara dry up?

about 13,000 years ago
By around 4200 BCE, however, the monsoon retreated south to approximately where it is today, leading to the gradual desertification of the Sahara. The Sahara is now as dry as it was about 13,000 years ago.

Can we irrigate the desert?

If sufficient water for irrigation is at hand, any hot, cold, sandy or rocky desert can be greened. Water can be made available through saving, reuse, rainwater harvesting, desalination, or direct use of seawater for salt-loving plants.

What happens if we put sea water in the desert?

If you take a small desert which is close to a sea-coast, it would still take enormous amounts of energy and exceptional engineering designs to pump in any significant amount of sea water into it. But if we get it done, what happens? Desert sand doesn’t pack very tightly, it is very loose and fine-flowing.

Can We bring marine water to the Mediterranean desert?

Some deserts in Egypt and Algeria lay below sea level, so bringing marine water to them would be cheap. There are many proposed scenarios to do very similar things: flooding the Siwa desert, desiccating the Mediterranean Some have already been put in practice.

What would happen if we brought in salty sea water?

By bringing in salty sea water there could be a risk of contaminating existing underground fresh water stores with salt, making such sources of water unusable. Also, by being salty, the water could not be used irrigate crops.

What would happen if we built a lake on the Earth?

One affect of creating such a lake would be a localized increase in humidity in the vicinity of the new lake, but nothing that would significantly increase rainfall. By bringing in salty sea water there could be a risk of contaminating existing underground fresh water stores with salt, making such sources of water unusable.
