Dujiangyan (都江堰）is a famous ancient irrigation scheme that lies at the foothills of the mountains. It is about an hour and half by car from Chengdu.
The builder title is credited to the governor of the ancient Qin state called Li Bing (李冰）. He lived during the Warring States period, which is about 2500 years ago.
There is a stone statue of him, with recognisable writing engraved on the rock paying tribute to him. The irrigation scheme prevented the water from the mountains from overflowing the Min river and flood the downstream irrigation area. He ordered the construction of irrigation head that consists of a fish mouth levee, and used it to divert large water flow into another stream, called the outer stream. Approximately 60% of water go into inner stream, while another 40% enter outer scheme during the flooding season.
A walk of about one half and hour is adequate for most visitors, to view the irrigation head, walk along the levees, cross the bridge, visit temples, exihibits etc. The more adventurous visitors could also walk and climb along the hilly right bank, and enjoy nice panaroma before making exit to the old street.
The Dujiangyan irrigation scheme lies close to the Dujiangyan city itself. This city was badly affected by the 2008 earthquake, though there are few signs that one can see. It seems to be most of the buildings have withstood the earthquake. There are also extensive building restoration or reconstruction works that still going on today.
