Due to the short time horizon after the ultimate impoundment of the Three Gorges reservoir (filling to 175 m normal pool mark) in 2009 and limited availability of monitoring data, some ecological and environmental consequences might not yet have surfaced.Nevertheless, a few new ecological and environmental problems have …
Abstract. Dams are often regarded as greenhouse gas (GHG) emitters. However, our study indicated that the world's largest dam, the Three Gorges Dam (TGD), has caused significant drops in annual average emissions of CO 2, CH 4 and N 2 O over 4300 km along the Yangtze River, accompanied by remarkable reductions in the annual …
Introduction. The Three Gorges Reservoir (TGR) is one of the largest water projects in the world. While it plays an important role in flood control and water utilisation, the TGR dramatically changes the incoming water and sediment conditions in the downstream reaches (Yang et al., 2007a; Zhang et al., 2017; Guo et al., 2019).Owing to …
