Effect of ice cover on stream flows and vertical mixing / by Y.L. Lau and B.G. Krishnappan. : En36-539/93-1980E-PDF
"In this report a turbulence model is used to calculate the flow structure for both free-surface and ice-covered conditions. It is shown that, in order to carry the same discharge, the flow depth will increase by about 10% to 30% when ice cover is present. The model also provides realistic predictions of the eddy diffusivity profiles. The results indicate that the mixing capacity of a stream is reduced when it becomes ice-covered and that this reduction in mixing is most pronounced if material is released into the the flow at the top"--Management perspective, page i.
