| Abstract: | Ecological water requirement(EWR)was proposed for ecological protection and construction,rational development and utilization of water resources research,etc.,which has been one of the global research focuses in recent years.On the basis of reviewing the advances in EWR research in domestic and overseas,we introduced the concept,characteristics and classification of EWR,and summarized the main calculating methods of EWR.At the same time,two calculating methods(Tennant method and Manning formula estimating method)and its practical application in environmental impact assessment of hydropower project were analyzed,finally,the development and application of EWR were prospected. |
