Aiming to achieve the goal of 'GREEN THREE GORGES', we are engaged indepth research on multifactor coupling and reciprocal effects, evolution and regulating mechanisms for reservoir ecosystems. To curb environmental pollution and maintain ecosystem integrity, we are further exploring the monitoring instruments and treatment equipment in hope of realizing industrialization. Meanwhile, we ...
That's exactly how the Three Gorges Dam affected earth's rotation. The Dam was made out of concrete which is a composite material of sand, gravel and cement. These component materials were stered around the earth's surface until it was collected and processed to make concrete. So, basically all the individual masses altogether resulted in a increase in mass in a particular position ...
· Three Gorges Dam can produce hydroelectric power of 100 billion kWh each year, which has been transmitted to almost 1/3 provinces of China. Hydropower is a clean energy.

The Three Gorges Dam is a prime example of a massive amount of materials used in the construction of such a massive project. The main materials used in the project were concrete and steel. Concrete has become a staple in almost every construction project in the world. It creates a strong foundation on which structures can stand or it is used to create stronger walls and ceilings. Around "10 ...
induced by the Three Gorges Dam (TGD) altered the lake balance by inducing greater discharge into the Changjiang River, which is probably responsible for the current lake shrinkage. Occasional episodes of arid climate, as well as local sand mining, will aggravate the lake recession crisis. Although impacts of TGD on the Poyang Lake recession can be overruled by episodic extreme droughts, we ...
