Abstract: Artificial destratification of lakes and reservoirs is used to influence a variety of water quality parameters. It relies on localized, vertical mixing of the water column and the subsequent redistribution of this mixed water by gravitationally driven intrusions. Under some conditions, a 2-D model is required to accurately simulate the vertical mixing, the spread of the intrusions and their subsequent re-entrainment. An extension of the lake simulation model DYRESM has been developed to model bubble plume destratification. Comparisons between field data and model predictions indicate the importance of the 2-D representation.
