Answer Details
Steep sides and often dry valleys in the desert are called "wadis". Wadis are usually formed by water erosion and are characterized by a wide, flat bottom and steep sides. During the rainy season, water flows through wadis and creates a temporary stream. However, during dry seasons, wadis are often dry, and they are used as pathways for human and animal migration in the desert. The term "wadi" is used primarily in the Middle East and North Africa.
