Abstract: The influence of a stable surface ice cover on the habitat conditions of a river as compared to open surface flow has been approached by analysis of the turbulent structure in the bulk of the stream and near the bottom. Provisional estimates are presented. Velocity data from rivers under both free surface and ice conditions are compared and discussed. Changes in the flow structure under winter conditions are presented in terms of mean velocity distribution and observed fluctuations of the longitudinal velocity components in the river. It is concluded that the ice cover may have significant effects on the local habitat, but further research is needed.
