Chemical reactions on the Yangtze

(May 17, 2010) In the rolling hills alongside the Three Gorges reservoir, on a Tiananmen Square-sized plot of land, stands a sign marking the site of an “Integrated MDI Project” in the village of Baishi. On completion, this will be home to the world’s largest Methylene diphenyl diisocyanate plant and the villagers all know that German chemical giant BASF is on the way.

Hot wind in the desert

(May 13, 2010) The Chinese county of Guazhou, in north-western China, is famous for its honey melons. But it also produces wind. It blows in from the east through the high, narrow valley formed by the Qilian and Beishan mountains, on the southern edge of the Gansu Corridor.

China intent on building more dams in a seismically-active region in Tibet

(May 6, 2010) After months of rumours, Chinese officials have confessed to plans to construct dams in a seismically-active and politically-sensitive region in Tibet’s Jiacha Canyon. The first dam — the 500-megawatt Zangmu hydroelectric project — is currently under construction and is the first of five planned for the scenic, 100-kilometre canyon on the Yarlung Tsangpo River.

“What I asked for and why”: Ren Xinghui’s epic quest to track down the costs of the Three Gorges dam

(May 3, 2010) In the afternoon of October 12, 2009, Chinese citizen, taxpayer, electricity consumer, and law graduate, Ren Xinghui, using the law his government had enshrined to protect Chinese citizens’ rights to information about government expenditures, exercised his right: he went to the offices of the Ministry of Finance and submitted a formal and legal request for the monies raised and spent to build the world’s largest hydro dam, Three Gorges on China’s Yangtze River. Here he explains what he asked for, why, and what happened next.

Forced evictions over Pubugou dam

(April 26, 2010) Authorities in the southwestern Chinese province of Sichuan have begun demolishing houses and forcing people from their homes near the Pubugou hydroelectic power project, which is due to go into operation soon. Chinese geological expert says the dam will increase the risk of devastating earthquakes.

The Zipingpu experiment: Dam engineers go back to the drawing boards

(April 20, 2010) Until the deadly Wenchuan earthquake in China in 2008, no large concrete face rockfill dam (CFRD) had ever been subject to a strong, ground shaking earthquake. But that changed on May 12, 2008 when the Zipingpu hydro dam, one of the largest CFRDs in China and sitting just 17 km from the earthquake epicenter, suffered higher than anticipated seismic forces, causing major damage to its concrete face and deflecting the giant structure 180 mm downstream. A leading scientist now says the earthquake should act as a wake up call for dam builders.

A Primer on Water

(April 19, 2010) Probe International has attached Luna B. Leopold and Walter B. Langbein’s report, “A Primer on Water” for our readers. Although the report is 50 years old, we believe it provides an excellent overview of water systems and water development.
