Many dams in Southwest China sustained significant damage after the recent massive earthquake.

The Min River and its tributaries have 30 dams upstream from Dujiangyan and 16 incurred significant damage from the recent earthquake. The Zipingpu dam is an example where a dam failure could have disastrous consequences.

Zipingpu dam threatens millions

The Zipingpu reservoir can hold a staggering 1.1 billion cubic meters of water, but the dam wall was cracked after the earthquake. Dujiangyan, with a population of 600,000 would be devastated by a dam failure first. Within a couple hours, water would then hit the provincial capital, Chengdu.

“Dujiangyan would be hit first,” says Environmental sciences professor Ai Nanshan. “You can imagine water levels as high as two-story buildings within 10 minutes. Everything would be gone. There would be no time to rescue anyone.”

Hydroelectric Dams and Chinese Demand for Electricity

There is an increasing demand in China for electricity, meanwhile concern about global warming soars. Although hydroelectric power seems like a good solution, the quantity, locations, and scale of such dams may not be ideal.

In addition to millions of people being displaced from the construction of dams, they also inhibited rescue efforts following the earthquake. Soldiers could have used boats, but dams eliminated this option.

“Here’s the contradiction: The country needs power for development,” says Professor Ai, chairman of the Chengdu Urban Rivers Association. “You open a map of China and you see that almost all of its rivers have been dammed. There are almost no rivers that flow naturally.

    1.1 billion cubic meters of water is nothing to play with. This will lead to the loss of thousands of lives and hundreds of millions of dollars in water damage restoration claims.

    Lets hop the the China Gov’t is proactive and not reactive on this one

    Poor planning by a centralized government has created a potential for further disaster……..China has a long standing history of disregard for the environment and its people
