Little impact of the Three Gorges Dam on recent decadal lake decline across Chinas Yangtze Plain
The ubiquitous lakes across China’s Yangtze Plain (YP) are indispensable freshwater resources sustaining ecosystems and socioeconomics for nearly half a billion people. Our recent survey revealed a widespread net decline in the total YP lake inundation area during 2000–2011 (a cumulative decrease of 10%), yet its mechanism remained contentious. Here we uncover the impacts of climate variability...
متن کاملTHE WHOLE DAM STORY: A Review of the China Yangtze Three Gorges Dam
Some marvel at these massive structures as engineering wonders that provide inestimable public benefit – things like flood control, water supply, hydroelectric power, improved navigation and water recreation. Yet others don’t share this appreciation and have doubts about the ability of humankind to effectively harness nature, particularly the power of the world’s mighty rivers. They decry the d...
متن کاملSedimentation in the Three Gorges Dam and the future trend of Changjiang (Yangtze River) sediment flux to the sea
The Three Gorges Dam (TGD) on the upper Changjiang (Yangtze River), China, disrupts the continuity of Changjiang sediment delivery to downstream and coastal areas. In this study, which was based on 54 years of annual water and sediment data from the mainstream and major tributaries of Changjiang, sediment deposition induced by the TGD in 2003–2008 was quantified. Furthermore, we determined the ...
متن کاملNew evidence of Yangtze delta recession after closing of the Three Gorges Dam
Many deltas are likely undergoing net erosion because of rapid decreases in riverine sediment supply and rising global sea levels. However, detecting erosion in subaqueous deltas is usually difficult because of the lack of bathymetric data. In this study, by comparing bathymetric data between 1981 and 2012 and surficial sediment grain sizes from the Yangtze subaqueous delta front over the last ...
متن کاملImpact of the Three Gorges Dam on the Hydrology and Ecology of the Yangtze River
Construction and operation of the Three Gorges Dam (TGD) has significantly altered the downstream hydrological regime along the Yangtze River, which has in turn affected the environment, biodiversity and morphological configuration, and human development. The ecological and environmental systems of the middle and lower Yangtze River have been affected adversely, with the ecosystems of Poyang La...
