Two senior Chinese water engineers have urged the central government to undertake a geological-safety inspection of new settlements being built in the Three Gorges area before the dam reservoir is filled next year.
The two prominent scientists – members of the Chinese Academy of Engineering who have played a key role in designing the Three Gorges project – are worried that construction in the reservoir area of new settlements for people displaced by the dam could trigger geological disasters and put lives at risk.
Impounding a huge body of water in the reservoir, which is scheduled to take place next June, is likely to activate at least 760 landslips, the respected experts write. Urgent action needs to be taken near urban areas, which face the threat of 21 potential landslips and 40 km of unstable riverbank.
Construction work now under way on a vast number of new settlements could also trigger geological disasters, they warn. Two cities, 11 county seats, 116 small towns and 6,301 villages are being relocated because of the dam. They say that what worries them most is that almost all of the new settlements are being built in a geologically fragile, mountainous region.
Although no previous dam project in China has included a geological-safety inspection, Mr. Wen and Mr. Zheng argue that the Three Gorges is a special case because of the region’s particular physical conditions. To ensure the safety of people resettled near the reservoir, they say expert teams must be sent in to undertake a careful, scientific appraisal of all the construction projects in the vicinity before the reservoir is filled.
China Daily reported earlier this month that “because of the complicated natural and geological conditions in the reservoir area, more than 70 landslides, collapses, and mud-rock flows have been recorded along its banks since 1982, killing about 400 people.”
