Opis

This book exposes practitioners and students to the theory and application of river and lake ice processes to gain a better understanding of these processes for modelling and forecasting. It focuses on the following processes of the surface water ice: freeze-up, ice cover thickening, 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 and modelling ice covers during the winter season and forecasting ice floods. Exercises accompany each component to reinforce the theoretical principles learned. These exercises will also expose the reader to different tools to process data, such a space-borne remote sensing imagery for ice cover classification. A thread supporting numerical modelling of river ice and lake ice processes runs through the book.

O autorze

Karl-Erich Lindenschmidt is an associate professor at the University of Saskatchewan.  He holds a Bachelor of Science in Mechanical Engineering from the University of Manitoba, a Master of Applied Science in Mechanical Engineering from the University of Toronto, a PhD in Environmental Engineering from the Technical University of Berlin and a Habilitation degree from the Technical University of Cottbus, Germany. Before his appointment at the University of Saskatchewan, Karl was with Manitoba Water Stewardship as a hydrologic modelling research engineer where one of his research topics involved monitoring and modelling river ice processes along the Red, Assiniboine and Dauphin Rivers. 

His knowledge on river ice processes aided Red River Floodway operations, the Ice Jam Mitigation Program along the lower Red River and flood risk management of the Lake St. Martin/Dauphin River system. He has also extended his portfolio of river ice work and research to include the Slave River in the Northwest Territories, the Peace and Athabasca rivers in Alberta, the South Saskatchewan and Qu’Appelle rivers in Saskatchewan and the Churchill and Exploits rivers in Newfoundland/Labrador.
