Abstract: Ice research dates back at least 80 years. Many results have been achieved; other topics have been left unsolved. There is a lack of results that can serve as guidelines for practical applications. A few pending topics are reviewed and discussed in this paper: 1) The viscosity and turbulent diffusion of water/frazil mixtures. 2) The formation and release of anchor ice. 3) The conditions for and the timing of disastrous ice runs. 4) Effects of ice cover and hanging dams on movable river beds are now actively studied due to the influence on habitat conditions under ice cover, but yet incompletely understood. 5) An unsolved problem is the correction of winter discharges under ice, obtained from ice free stage recordings. This is closely connected to under-ice friction under varying conditions and also related to the other topics mentioned.
