Explain why deltas and flood plains have been important to the development of human civilization

Rivers were crucial to the survival of early civilizations because they were responsible for providing a source of water, irrigation for good farmland and a way for people to trade with other people through water transportation. Many of the earliest civilizations thrived due to the availability of rivers such as Mesopotamian cultures with the Euphrates River and Tigris River, Egyptians with the Nile River, Indians with the Indus River and Chinese with the Huang River and Yangtze River.
