Ice Hydraulics

Since the early sixties, Lasalle | NHC has published a number of scientific papers that are still quoted as references today when it comes to the theoretical aspects of river ice hydraulics. Initially, Lasalle | NHC’s expertise was focused on calculations of flood water levels due to the influence of frazil ice accumulations or ice jams. However, Lasalle | NHC has broadened its activities over the years and has been involved in numerous projects covering all the aspects of river hydraulics in Northern regions. Depending on the project’s objectives, the appropriate tool – numerical or physical modeling – is selected to perform the study.
