INTRODUCTION
The
most topical and controversial large dam scheme is undoubtedly the Three
Gorges Dam on the Yangtze River, China. It will be the largest man-made
structure in the world. It has been constructed not only for flood
protection, navigation and hydroelectric power generation purposes, but
as a political statement to the world. The impact on the local
populations has been immense, involving relocation of over a million
people, the abandonment (and eventual inundation under dam waters) of
entire cities, the drowning of archaeological sites, and destruction of
the wildlife and habitats during construction.
