“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.

The origins of the Sahara desert, the largest hot desert and the largest desert in the world, date back to approximately 600 million years ago. The sea submerged the region over and over again, depositing its sediments; whenever it resurfaced, it was alternately covered by forests, savannahs and even marshlands.
