Abstract: The paper represents an analysis of the concept for the control of the ice regime on the Yugoslav reach of the river Danube. The largest part of this reach is under the influence of the backwater from the Iron Gate Dam I. After its construction, the hydraulic and morphological factors influencing the ice regime on the Danube changed significantly. As a result, the concept of the ice control is based on the analysis of the natural regime (before the dam was constructed) and the character of the changes that occurred. The adopted ice protection concept requires that the natural conditions of the ice regime should be established. This should be done by lowering the water level in the reservoir as well as by using icebreakers that need to cut the ice cover and in this way enable the faster evacuation of ice along the reservoir. Some elements of this concept for the control of the ice regime were tried out and checked during the winter of 1981/82 when the ice cover had formed on the entire Yugoslav reach of the Danube. The existing experience has shown that the adopted ice control concept represents a good basis for successful ice protection.
