Winter floods caused by ice jams are one of the most damaging natural hazards in Canada. They can impact public infrastructure, winter transportation and riverside neighborhoods or industries. Efforts are already made to predict location, extent and timing of river ice jams. Including citizens, academics, governments and corporations into this process can further reduce vulnerability to river ice jams and increase awareness and knowledge of the phenomenon.

This poster shows examples of river ice monitoring that optimize the use of existing tools and increase public participation in risk management projects. Two initiatives will be presented as examples of collaborative science: (1) ensemble based decision making in river ice type mapping from satellite and optical images and (2) crowdsourced data collection via mobile app. Both approaches increase the number of people involved in river ice jams risk management and promote an open and decentralized scientific agenda.

This study is part of the DAVE project funded by Defence Research and Development Canada’s (DRDC) Canadian Safety and Security Program (CSSP). DAVE, which stands in French for Dispositif d’Alerte et de Vigilance aux Embâcles de glace, is a project which aims to improve ice jam risk management across Canada.
