Abstract:To explore eutrophication and algal bloom mechanisms in channel type reservoirs,a novel enclosure experiment was conducted by changing light intensity (LI) in the Daning River of the Three Gorges Reservoir (TGR).Square enclosures (side 5.0 m) were covered on the surface with shading materials of different thickness,and with their bases open to the river.Changes and characteristics of the main eutrophication factors under the same water quality and hydrodynamic conditions but different LI were evaluated.All ...
Keywords:eutrophication  algal bloom  enclosure experiment  channel type reservoirs  Three Gorges Reservoir
