Dujiangyan Irrigation History
Origins and Li Bing
The story of the dujiangyan irrigation system started over two thousand years ago. People on the Chengdu Plain had many floods from the Min River. These floods ruined crops and made life hard. Archaeologists found old water systems at the Hongqiaocun Site from 4,000 years ago. This shows people knew about irrigation long before the famous project.
Li Bing was very important in building the dujiangyan irrigation system. He worked as an administrator and engineer for the state of Qin. This was during the Warring States period. Li Bing led the building of the system to stop the Min River from flooding. He studied the river and made a plan to control the water. His work helped farmers grow more food and made life better. Today, people can see statues and memorials for Li Bing in dujiangyan old town.

- He worked for the state of Qin and led the building of the dujiangyan irrigation system.
- Li Bing’s work fixed the Min River floods that hurt local people.
- He studied the Min River to control its water and help farming.
- The dujiangyan irrigation system helped Sichuan grow and is a UNESCO World Heritage Site.
Ancient Construction Techniques
The builders of the dujiangyan irrigation system used smart methods. They did not use dams to block the river. Instead, they made a system that worked with the river’s flow. Each main part of the system had a special job.
| Component | Function |
|---|---|
| Fish Mouth | Diverts flow to the intake stem channel |
| Flying Sand Sluice | Manages flood and sediment |
| Baopingkou | Controls water intake and flood management |
Workers shaped the riverbanks and built stone walls by hand. They used bamboo cages filled with stones to make the banks strong and guide water. These ways helped the dujiangyan irrigation system last a long time. The design let people control floods, manage sand, and send water to fields without hurting nature. People in dujiangyan old town still respect these old building skills.
Legacy in Sichuan
The dujiangyan irrigation system changed Sichuan forever. After it was finished, the Chengdu Plain became a top farming area in China. The system watered about 6,700 square kilometers of land. This helped farmers grow rice, wheat, and other crops. More people moved to the area because farming was good. Towns and cities grew bigger.
| Evidence | Description |
|---|---|
| Agricultural Prosperity | The dujiangyan irrigation system has helped farming in the Chengdu Plain for over 2,000 years, watering about 6,700 km². |
| Attraction of Settlers | Building the dujiangyan irrigation system around 256 BCE made the Chengdu Plain better for farming, so more people moved there. |
Today, the dujiangyan irrigation works still help farming and give water to millions. The system shows how people can work together and be creative. Visitors can see the old irrigation works and learn how they changed Sichuan’s history and culture.
How Dujiangyan Irrigation Works

The dujiangyan irrigation system has three main parts. Each part does a special job. They work together to stop floods and help farming in Sichuan.
Yuzui Water-Dividing Weir
The Yuzui Water-Dividing Weir is in the middle of the system. Engineers made it look like a fish mouth. This weir splits the Minjiang River into two streams. One stream is called the inner stream. The other is the outer stream. The inner stream is deep and narrow. It carries most water when it is dry. The outer stream is wide and shallow. It takes the rest of the water. It also washes away silt and dirt.
| Feature | Inner Stream | Outer Stream |
|---|---|---|
| Depth | Deep and narrow | Shallow but wide |
| Flow Distribution | Carries about 60% of water in dry times; drops to 40% in floods | Takes the rest, cleaning out silt and dirt |
The Yuzui Weir keeps water clean and steady. Farmers need this steady water for their crops. The design uses the river’s shape to move water. It does not block the river.
Tip:
The Yuzui Weir splits water by season. This keeps fields wet and stops floods.
The Yuzui Weir uses smart ideas. It splits the river, controls water, and manages dirt. The Feisha Dike helps keep silt out of the inner river. The bottle-neck channel controls how much water goes to farms.
| Component | Function |
|---|---|
| Fish Mouth (Yuzui) | Splits the river into two streams to manage water in different seasons. |
| Feisha Dike | Keeps silt out of the inner river using science. |
| Bottle-neck channel | Controls water to farms through a narrow channel. |
Feishayan Flood Diversion
The Feishayan Flood Diversion is like a safety switch. It sits next to the Yuzui Weir. When water gets high, Feishayan lets out extra water and dirt. This stops the inner river from flooding. The structure keeps the Chengdu Plain safe from floods.
When there is too much water, Feishayan sends it to the outer river. This helps stop floods. It also removes silt and keeps the system working. Farmers count on this flood diversion to keep their fields safe.
Note:
Feishayan lets out extra water and dirt by itself. This keeps farms safe and the system working well.
Baopingkou Water Inlet
The Baopingkou Water Inlet is a narrow channel. It controls how much water goes into the system. When it is dry, Baopingkou lets about 60% of the river’s water into the inner river. When there are floods, it changes the flow to protect the Chengdu Plain.
Baopingkou balances water for farming and stops floods. It acts like a gate. When water gets too high, Baopingkou keeps floodwater out. This gives farmers steady water and keeps the area safe.
The Baopingkou Water Inlet shows how old engineers managed water well. They made sure farmers had enough water for crops. They also kept towns safe from floods.
Impact on Flood Control and Agriculture
The dujiangyan irrigation system helps stop floods and supports farming. The three main parts work together. They guide water, remove silt, and stop floods. Farmers get steady water for their fields. Towns stay safe from high water.
- Yuzui Weir splits water and keeps it steady.
- Feishayan Flood Diversion lets out extra water and dirt.
- Baopingkou Water Inlet controls water and stops floods.
This system helped Sichuan become a great farming place. It shows how smart ideas can fix big problems. People still use dujiangyan for farming and flood control today.
