The Dujiangyan Irrigation System, located on the Minjiang River near Chengdu in Sichuan province, China, is an ancient feat of engineering and a UNESCO World Heritage site. Constructed around 256 BC under the guidance of local governor Li Bing, this system was designed to control flooding and provide water for agriculture. It cleverly uses the natural terrain and waterways to create an infrastructure that has continuously functioned for over two millennia. Dujiangyan's key components include the Fish Mouth Water-Dividing Dam, which splits the river into an inner and outer stream to help distribute the flow of water, and the Flying Sand Spillway, which diverts sand and stones from the river. There's also the Bottle-Neck Channel, which controls the amount of water entering the irrigation system. This system has turned the Chengdu Plain into one of China's most fertile regions, contributing significantly to its wealth and prosperity. This innovative non-dam irrigation method has been recognized for its harmonious relationship with the environment and its sustainable benefits to the local community.
It is an amazing irrigation project designed to divert water from flooding since 300BC
It is based on law of physics with the flow dynamics diverting water away to prevent flood

Nice UNESCO site that was built since 256 BC and still operational today. Apparently provides some of the irrigation, flood control and water consumption for some parts of sichuan province
Fairly cro..
This engineering feat is about 60 km from downtown Chengdu and takes about 90 minutes to get to.
It’s amazing how they were able to plan this system that serves primarily two purposes – avoid floodi..
We didn't do a guided tour and approached the area from Erwang Temple by foot across the Anlu suspension bridge. Great way to spend a half-day and avoid the crowds. Irrigation system is definitely an ..
It is amazing to know that the Chinese were capable of such irrigation back in the olden days. The scale, the study and the sacrifice that the people to make it happen, and more importantly the patie..
