Abstract: Water and thermal regime determine jointly the ice regime, which includes ice formation and movement, build-up, duration and break-up of the ice cover. The basic principles of the calculation of the thermal regime and its application to forecasting the ice regime are summarized with references to operational applications. The results of a survey made by the World Meteorological Organization (WMO) are evaluated. Problems related to the observation of the phenomena needed for operational ice forecasting are also discussed with the conclusion that their improvement is desirable. A system of ice forecasting is outlined. The aspects of the winter operation of hydraulic structures with allowance for the forecasts are briefly mentioned. The necessity of feedback from the operator to the forecasting centre is underlined. Finally, conclusions are derived and suggestions are made. The latter include the elaboration of the principles of a complex ice forecasting system within the framework of the Hydrological Operational Subprogramme of WMO, in cooperation with the IAHR.
