It is true that Three Gorges Dam has a great ability to adjust and restore flood with the reservoir capacity of 39.3 billion cubic meters, which could reduce the damage of Yangtze River flood, especially for the section in Hubei.Three Cups of Tea has 161,521 ratings and 19,515 reviews. Sarah said Here are a few things Im suspicious of1. Sarah said Here are a few things Im suspicious of1. A book with two authors.An increase in the river-lake water level gradient 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.
