Dujiangyan Irrigation Project of China

 

 

 
Over 2,200 years ago, Chengdu was threatened by the frequent floods caused by flooding of the Minjiang River (a tributary of the Yangtze River ). Li Bing, a local official of Sichuan Province at that time, together with his son, decided to construct an irrigation system on the Minjiang River to prevent flooding. After a lengthy study and a lot of hard work by the local people, the great Dujiangyan Irrigation Project was completed. Since then, the Chengdu Plain has been free of flooding and the people have been living peacefully and affluently. Now, the project is honored as the 'Treasure of Sichuan', which still plays a crucial role in draining off floodwater, irrigating farms and providing water resources for more than 50 cities in the province.
 
Dujiangyan is the oldest and only surviving no-dam irrigation system in the world; and a wonder in the development of Chinese science. The project consists of three important parts, namely Yuzui, Feishayan and Baopingkou scientifically designed to automatically control the water flow of the rivers from the mountains to the plains throughout the year.
 
 
There is a magnificent bridge called the Anlan Cable Bridge crossing the Minjiang River above Yuzui, which is the most scenic place in Dujiangyan. Seen from afar, the bridge looks like a rainbow hanging over the river. From the bridge, you can clearly see the entire layout of the Dujiangyan system.
