Study on Eco-environmental Problems and the Water Requirement of the River Dry-up Section of Small Hydropower Project

Hydropower is a kind of reproducible energy with high quality. Recently, construction of small hydropower project has promoted the economic and social development of Zhejiang Province, China. This paper studies the eco-environmental problems in the dry-up river section of hydropower project, defines the terms related, and discusses the methods of calculating eco-environmental water requirements. The impacts of different eco-environmental water uses on the hydropower generation benefit are analyzed, and the benefit losses are estimated using Tennant method.
