Alluvial desert

From Wikipedia, the free encyclopedia

Alluvial describes rich, fertile soil deposited by rivers and streams, so the alluvial desert is a desert that has been created from two large rivers leaving behind their rich, fertile sediments. The world's first civilization, which was Mesopotamia, developed in this region in between the Tigris and Euphrates Rivers. At one time, it was believed that they began food production here because of the rich soil, but although there was this rich soil present, it was still necessary for them to invent irrigation in order to successfully farm this alluvial desert.
