Abstract: This paper deals with some aspects of the complicated interaction between ice and water in rapids. The general background are both recent and year long collection ofinformation from field research and obseIVations. Among topics included are: - The ice regime in rapids: Thermal balance, ice forms and typical processes - The influence of local geometry and hydraulics on the ice regime - The flow regime in ice covered rapids: Effects of anchor ice (bottom ice) forming on the bottom in modifYing cross sections and fiiction, and influencing on the general flow pattern, velocity distribution and water levels. - The static stability and geometry of anchor ice dams, and limiting factors for the size of the darns. - Converted potential energy as a cause for decay of ice dams.
