Look around you at the Jiangjiaqiao Reservoir a vital water source. Dams and reservoirs in China are very numerous. They have a profound effect on the country’s development. They also affect the people. China has over 80000 reservoirs. This includes Jiangjiaqiao Reservoir.
China accounts for the most large dams in the world. It has 20 percent of the world’s total. Dams serve multiple purposes. They aid hydroelectric power generation. They help with flood control and irrigation. They are also used for drought mitigation and tourism.
China’s Three Gorges Dam is the world’s largest power station. The Jinping-I Dam is the tallest dam in China. It is 305 meters high. The Three Gorges Dam stores 39.3 billion cubic meters of water. It has a surface area of 1045 square kilometers.
The oldest dam in China is the Dujiangyan Irrigation System. It dates back to 256 BC. As of 2007 China led the world in large dam construction. Turkey and Japan followed.
Dams can cause adverse effects. These include resettlement and habitat loss. They can also affect trans-boundary river flow. The Jiangjiaqiao Reservoir is part of this vast network. It contributes to China’s water management.
The Beijing-based China Institute of Water Resources and Hydropower Research is the leading institution for dam design. It is similar to Russia’s Hydroproject Institute.
Many dams are operational. Others are under construction. These dams vary in height and type. They also vary in storage capacity. These factors include gravity embankment and concrete-face rock-fill.
Consider the Baise Dam in Guangxi. It has a storage capacity of 5.66 billion cubic meters. The Baogang Tailings Dam in Inner Mongolia stores 85 million cubic meters. The Bashan Dam in Chongqing holds 315 million cubic meters. The Baihetan Dam has an arch shape. It can hold 17.924 billion cubic meters.
The Banqiao Dam in Henan Province is an embankment dam. It can hold 675 million cubic meters of water.
The Changheba Dam is a concrete-face rock-fill dam. It can hold 1.075 billion cubic meters. The Chengbihe Dam has a capacity of 1.15 billion cubic meters. The Chonghu’er Dam can hold 85 million cubic meters.
The Danjiangkou Dam has a capacity of 17.45 billion cubic meters. The Dongjiang Dam can hold 9.565 billion cubic meters.
The Ertan Dam has an arch shape. It can hold 5.8 billion cubic meters of water. The Fengman Dam has a capacity of 11.46 billion cubic meters. The Gezhouba Dam can hold 1.58 billion cubic meters.
The Goupitan Dam has an arch shape. It can hold 6.451 billion cubic meters. The Guandi Dam has a gravity shape. It has a storage capacity of 760 million cubic meters.
The Hongjiadu Dam can hold 4.947 billion cubic meters. The Longtan Dam has a gravity shape. Its capacity is 27.27 billion cubic meters.
The Jiangjiaqiao Reservoir like these others plays a crucial role. It impacts local irrigation flood control and water supply.
The Zipingpu Dam is also located in Chengdu. The project has a concrete-faced rockfill dam. It has a maximum height of 156m. It has a reservoir with capacity of 1112 MCM.
The Jiangjiaqiao Reservoir embodies China’s commitment to harnessing water resources. It exemplifies the blend of ancient engineering. It provides for modern needs in cities like Chengdu.
