Abstract: River ice research has largely been driven by engineering and environmental problems that concern society. These concerns have been on ice jam flooding, hydropower operation, inland navigation, winter time ecology, and the influence of ice on water quality. River ice phenomena include formation, evolution, transport, accumulation, deterioration, and dissipation of various forms of ice. These phenomena involve complex interactions between hydrodynamic, mechanical, and thermal processes, under the influence of meteorological and hydrological conditions as well as the operations of water resources engineering projects. There has been only a relatively small group of researchers engaged in this non-traditional topic in hydraulics. However, important advances have been made in the last couple decades since the establishment of the IAHR Committee on Ice Research and Engineering. The research into river ice problems in the last few decades has led to significant improvements in our understanding on river ice processes. In this paper, major developments on river ice research will be reviewed along with discussions on areas that are in need of further advancements. These will include the research advancements on frazil and anchor formation, ice jam dynamics, frazil jam/hanging dam evolution, breakup processes, sediment transport with ice effects, and mathematical modeling of river ice processes.
