Encyclopedia
The Ankang Dam is gravity dam
on the Hanjiang (Han) River near Ankang
in Shaanxi Province, China
. The main purpose of the dam is hydroelectric power production along with other purposes such as flood control and navigation. The dam withholds a 2580000000 cubic metre reservoir which supplies water to its powerhouse located on the right toe. The power station contains 4 x 200 MW generators for a total installed capacity of 800 MW. On the dam's surface adjacent to the power house are five controlled spillway
chutes. The dam also houses five mid-level openings and four base openings for discharging water as well.
Construction on the dam began in 1978 and the dam structure was complete on December 23, 1989. Almost a year later on December 12, 1990, the first generator became operational. It was not until December 25, 1992 that all four generators were operational and by 1995, the entire project was complete.

Spillway
A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically being the river that was dammed. In the UK they may be known as overflow channels. Spillways release floods so that the water does not overtop and damage or even destroy...
