This book exposes practitioners and decision-makers to the theory and application of river ice processes to gain a better understanding of these processes for modelling and ice flood hazard and risk assessment. It focuses on the following processes of the surface water ice: river freeze-up and flooding, mid-winter ice-cover breakup and flooding and end-of-winter ice-cover breakup and ice jamming. The reader will receive a fundamental understanding of the physical processes of each component and how they are applied in monitoring, modelling and flood hazard/risk assessment of river ice during the entire winter season, from freeze-up to potential mid-winter breakup and concluding with springtime ice-cover breakup and ice-jam flooding. Spreadsheet, geographical information system (GIS) and modelling exercises accompany each component to reinforce the theoretical principles learned. Step-by-step tutorial videos allow the reader to better engage with the book and learn the material faster.
