Abstract: Understanding ice formation, calculating stage-discharge relation for ice-filled or ice-covered streams, predicting river-ice breakup and analyzing ice jams, are of central importance to ice engineering in the Nordic countries. Ice production in various rapid river sections differs, although the meteorological conditions are similar. Control of ice conditions must be based on an understanding of the hydraulic conditions in the rivers and on the nature of ice formation in running water. The first part of this short paper gives a synopsis of the hydraulic conditions in open and ice-covered rivers. The second part gives a survey of present possibilities for control of ice production. From a hydraulic standpoint, the stabilization of ice conditions has, until now, been little explored. The purpose of this contribution must be regarded as indicating the need for a broader interest in ice problems in the future.
