AbstractThis review paper presents background information on the process of river break-up and control of ice during break- up. The main factors affecting break-up are briefly outlined. As the process of break-up depends on variable weather conditions and on local variations in channel morphology, break-up patterns vary from river to river and from year to year for a given section of river. The limitations and main problems associated with various control methods are summarized. Economic and local site conditions usually determine not only the method but also the extent to which river ice can be controlled. All methods of control have the basic requirement of being able to handle successfully the worst ice conditions likely to occur. Forecasting the different events associated with break-up is thus an important part of river ice control.
