The Yellow River is the second-longest river in China, after the Yangtze River, and the sixth-longest river system on Earth at the estimated length of 5,464 km (3,395 mi). Originating at an elevation above 15,000 feet in the Bayan Har Mountains, it empties into the Bohai Sea. The Yellow River basin was the birthplace of ancient Chinese civilization. Its yellow sediments are carried downstream from the Loess Plateau. The river experiences frequent devastating floods and course changes produced by the continual elevation of the river bed, sometimes above the level of its surrounding farm fields.
