Summary
BEIJING-- As work continues on the 1600-meter-long, 185-meter-high Three Gorges Dam, engineers and scientists are debating ways to slow the buildup of silt in the 690-kilometer reservoir it will create as well as how to minimize environmental disruptions.

As presently planned, the $30 billion project, scheduled to begin generating power in 2003, will also uproot an estimated 1.2 million people.
