摘要：

Possible management strategies to improve water quality in a eutrophic water supply reservoir in Argentina were evaluated using the one-dimensional coupled hydrodynamics and water quality model DYRESM-CAEDYM. The model was used to determine the effects of several different artificial destratification system designs (including both bubble plume diffusers and surface impellers with draft tubes, both separately and in combination), on the biomass of the potentially toxic cyanobacteria Microcystis aeruginosa. The best results were found by using a combination of a deep and shallow diffuser, to break down the seasonal thermocline and therefore limit sediment nutrient release and anoxia, and to enhance vertical mixing in the surface mixed layer, respectively.
