Title: Impact of the Three Gorges reservoir operation with different schemes on the downstream ecological water use
Abstract: With population increase and economic growth,the flow regime of the Yangtze River has been altered to some extent by human activities,and particularly by dam construction.Dam-induced alterations in the flow regime will unavoidably influence water allocation among different water uses and instream ecological water requirements may not be satisfied.To assess the impacts of the Three Gorges reservoir operation on the downstream minimum instream ecological water requirements,this paper selected this reservoir and the Yichang hydrological station below the reservoir as case study sites.The reservoir outflows of two water storage schemes were simulated using the long-term time series of daily discharge data,and a satisfaction factor for the downstream minimum ecological flow was computed.This work would provide references for the integrated management of the river's water resources and the assessment of dam-induced impacts on the river's ecosystem health.
