Includes bibliographical references. "Sub-aqueous disposal of mine tailings is a technique whereby a mixture of water and finely ground rock is pumped to the bottom of a water body. Material from the slurry settles and consolidates forming a new lake bed with an overlying layer of water with high levels of dissolved material. The premise is that the water forms an inert cap, effectively containing the injected material. Environmental considerations require that the effectiveness of this storage method be explored. Here, we describe a modelling application to the Brenda Pit Lake using an extended version of the lake and reservoir water quality model, DYRESM, incorporating algorithms for detailed ice cover, heat fluxes and also internal wave-driven boundary mixing. Sheltering and shading of the meteorological forcing is taken into account in the model. Both the field data and the model confirm the capping effect of the relatively salty water in the pit"--Abstract. gccst Mining industry gccst Water quality Stevens, C. R., author.
