小浪底

The damsite for the Xiaolangdi Dam (小浪底) which is now being constructed (scheduled for completion in 2002). To gain reservoir storage capacity, the low-lying land in the foreground will be submerged resulting in a resettlement population of 400,000 persons. Still, the reservoir can only last for 30-50 years because of heavy sediment deposition.

I took the following picture while I visited the damsite in 1994, showing the construction of the cement-grout apron to reduce seepage flow under the dam, which is a rockfill dam constructed on top of the river sediment.
