Dujiangyan Irrigation Project of China

Location of Dujiangyan Irrigation Project of China

 

In China, Chengdu is always commended as Tian Fu Zhi Guo, refers to "Nature's Storehouse". It is recorded that more than 2,200 years ago, the city was always faced the threat by the frequent floods caused by flooding of the Minjiang River. In order to control the flood, Li Bing, a local official of Sichuan Province then, with his son, decided to build an irrigation system on the Minjiang River.

 

Features of Dujiangyan Irrigation Project of China

 

After a careful research and long-time hard work, the great Dujiangyan Irrigation Project was finally completed. Since then, the Dujiangyan Irrigation Project has contributed a lot to the prevention of the flood and the Chengdu Plain has been free of flooding, the folks, at last, lived a peaceful and affluent life. Till now, the project is still crowned as the "Treasure of Sichuan", since it plays a crucial role in irrigating farms and providing water resources for more than 50 cities in the province, and the most important, draining off floodwater.

All over the world, it is hardly to find another ittigation system as Dujiangyan -- the oldest and only surviving no-dam irrigation system. It is a miracle in the history of Chinese science.

There are totally three important parts: Yuzui, Baopingkou and Feishayan exquisitely and scientifically designed to automatically control the water flow from the mountains to the plains all the year round.

Yuzui, accquired the name for it resembles a big fish lying in the Minjiang River. It is a watershed dividing the river into two parts: inner river and outside river; Baoping Kou, like a neck of a bottle, bringing water into the inner river from Minjiang; Feisha Yan is a spillway that passes the sand and stones of the inner river into the outer river. Meanwhile, Baoping Kou controls the amount of the intake water owing to its advantageous location. These three parts cooperate with each other perfectly, forming an effective water conservancy project.

Thanks to Dujiangyan Irrigation Project, since its completion, during the low-water season, only 60% of the Minjiang water is brought into the inner river for irrigation while another 40% is drawn into the outside river, while it goes in the reversed way in the flood season in order to ensure the water supply for irrigation and protection from flooding on the Chengdu Plain.

A fantastic bridge, Anlan Cable Bridge went across the Minjiang River above Yuzui, which is the most well- known scenic spot in Dujiangyan. From afar, the bridge seems just like a rainbow hanging over the river. From the bridge, you can clearly see the entire layout of the Dujiangyan system. The construction of the bridge initially started before the Song Dynasty (960-1279), when the main body of the bridge was built with wooden blocks and the handrails were made of bamboo. Recently the wood and bamboo were substituted with steel and reinforced concrete to ensure the security of the visitors.
