Fish Mouth Levee (Yuzui) of Dujiangyan irrigation system, Chengdu, Sichuan Province, China

Dujiangyan is an irrigation infrastructure built in 256 BC. It is located in the Min River in Sichuan, China.The Fish Mouth Levee, named for its conical head that is said to resemble the mouth of a fish, is the key part of Li Binga??s construction. It is an artificial levee that divides the water into inner and outer streams.The inner stream is deep and narrow, while the outer stream is relatively shallow but wide. This special structure ensures that the inner stream carries approximately 60% of the rivera??s flow into the irrigation system during dry season. While during flood, this amount decreases to 40% to protect the people from flooding. The outer stream drains away the rest, flushing out much of the silt and sediment.Dujiangyan is still in use today to irrigate over 5, 300 square kilometers of land in the region
