This workshop will examine the technical foundations that enable effective flood risk management in Southern Ontario – from the data we collect to the tools we use to analyze and communicate flood information. Participants will explore how hydrometric networks, satellite monitoring, hydraulic modeling software, and sensor technologies work together to create flood information systems, while examining how these technical choices can either support or hinder equitable access to critical flood data. Special guest speaker Dr. Rodrigo Costa from the University of Waterloo will speak about regional risk modeling and innovative approaches to simulating how disasters affect different communities. Together, we will examine the limitations of current technologies and their connection to equity outcomes, exploring how we might redesign data collection, processing, and dissemination systems to better serve all communities and support more equitable flood risk management across Southern Ontario.
