Abstract: A substantial part of inland waters is covered every year with ice during periods of low air temperatures. This seriously impedes their utilization for power generation, navigation, water supply, sanitary purposes, etc. In recent years much attention has been directed to control and mitigate negative consequences of ice phenomena on hydraulic engineering projects. The paper presents ice problems which appear during the operation of hydropower installations and hydraulic structures. These problems are present with various intensities during periods of ice formation, ice cover duration, and break-up and ice passage. In hydropower installations, head losses due to ice cover formation, clogging of water intakes and operation of pump-storage power plants are discussed. Ice problems in hydraulic structures include the formation of ice cover and ice jams with possible flood danger, passage of ice cover through the weirs, and operation of navigation locks and channels. Examples of various engineering ice control measures to improve operation and safety of hydraulic structures are presented.
