Seismic signs

(September 5, 2012) Probe International has been at the forefront of research on the connection between seismic activity and large-dam construction, focusing on examples in China such as the Zipingpu Dam, which is thought to have triggered the deadly 2008 Sichuan earthquake. Now, a new article by U.S.-based quake warning advocate, David Nabhan, calls for a rethink of seismic forecasting in North America that draws on connections so often overlooked: specifically, the trigger effect of dams, and the impact of lunar and solar gravitational tides on earthquake activity.

Big, complicated, hard to manage

(September 1, 2012) The staggering costs of China’s Three Gorges Dam—the displacement of 1.7 million and counting, and a price tag six-times the original estimate—are well known. But the enormous project’s complicated operational demands are largely unknown, and they promise to get more vexing as more dams are built upstream. Power magazine looks at the complexities of delivering power from such large-scale hydropower plants trans-region, trans-province, and trans-basin and the pressing need for peak regulation, frequency regulation, and emergency reserves for hydropower plants.

10 most expensive energy projects in the world

Surprisingly, CNN put China’s behemoth Three Gorges Dam ‒ at a cost of $28 billion ‒ in last place for the ‘honour’ of world’s most expensive energy project. In fact, had CNN used the most recent cost figures for Three Gorges, the world’s largest dam would have come in second place (at $60 billion) between the $116-billion Kashagan oil field in Central Asia and the $57-billion Gorgon gas project in Australia.

Too many masters

(August 20, 2012) A severe test of the Three Gorges dam’s capacity to withstand a major flood peak in July initially showed the mighty dam ready and able. However, downstream areas found themselves at higher risk when floodwaters were released by the dam. Meanwhile, upstream areas are impacted when the dam holds floodwaters back. This article looks at the many pressures, and potential disasters, weighing on the ability of China’s biggest dam to fulfill its design mandate and asks: is July’s flood peak—the biggest test of the dam so far in its nine-year history—just the start?

Storm of conscience

(July 27, 2012) The force of a powerful storm that struck Beijing over the weekend has exposed massive flaws in the capital city’s antiquated plumbing infrastructure. Chinese authorities in Beijing now face a firestorm of criticism from citizens demanding to know why their drainage system—famously defined as a city’s conscience by French writer Victor Hugo—was neglected for so long. The weekend flooding has also brought into question the official death toll, which many feel the government is downplaying to offset blame for the city’s poor emergency response to a disaster that could have been more manageable.

China’s new mega-dam is a mega-problem

(July 12, 2012) Almost 20 years in the making, China’s Three Gorges mega-dam was declared complete on July 4 when the last of its 32 generators went online, 10 years after the first turbine went into operation. There is no end in sight, however, for costs associated with the vast and controversial project, which remains closer to disaster than triumph.
