The Ural River is one of the two major rivers (the other is the Volga) that empty into the northern coast of the Caspian Sea, creating extensive wetlands. This image shows details of the Ural’s tree-like (or “digitate”) delta. This type of delta forms naturally when wave action is low, and sediment content in the river is high. New distributary channels form in the delta when the river breaches natural levees created by sediment deposition. The long main channel of the river in this image and several of the distibutary channels are too regular to be entirely natural, however. Like the famous Mississippi River delta in the United States, the Ural River delta has been significantly modified to reduce flooding and divert water.
