In a significant advancement for Canada's resilience against escalating flood risks, McMaster University professor Paulin Coulibaly has secured substantial new funding to propel the Canada-wide flood forecasting network into its next era. Known as FloodNet2, this initiative builds on the foundational work of the original FloodNet project, aiming to revolutionize how the nation predicts and mitigates devastating floods. With climate change amplifying the frequency and intensity of extreme rainfall events, this McMaster-led effort underscores the pivotal role of higher education institutions in tackling national challenges through collaborative research.

Floods represent Canada's most prevalent natural disaster, surpassing wildfires, earthquakes, and tornadoes in occurrence. According to Statistics Canada, approximately 80 percent of Canadian cities are situated wholly or partially on floodplains, heightening vulnerability. Recent events, such as the July 2024 Toronto deluge that dumped 97.8 millimeters of rain in three hours—far exceeding the monthly average—resulted in nearly $1 billion in insurable losses alone. Insured damages from severe weather, dominated by floods, topped $2.4 billion in 2025, marking the tenth costliest year on record and highlighting the urgent need for improved forecasting capabilities.

🌊 The Genesis and Achievements of FloodNet Phase 1

The story of FloodNet begins in 2014 when Coulibaly, then assembling a dream team of experts, secured a landmark $5 million Strategic Research Network Grant from the Natural Sciences and Engineering Research Council of Canada (NSERC). Hosted at McMaster University, this multi-disciplinary consortium brought together hydrologists, engineers, climate scientists, and end-users from across the country to address fragmented flood modeling practices. Prior to FloodNet, provinces, municipalities, and hydropower companies relied on disparate, often sub-optimal models, lacking the standardization seen in the United States where all 50 states employ unified systems.

Over its initial six-year run, FloodNet organized research into four interconnected themes: analyzing historical and future flood regimes (led by University of Waterloo's Donald Burn and McGill's Van-Thanh-Van Nguyen), reducing predictive uncertainties (Université Laval's François Anctil), developing the Canadian Adaptive Flood Forecasting and Early Warning System (CAFFEWS, co-led by Coulibaly and Waterloo's Weihua Zhuang), and assessing physical, socio-economic, and environmental impacts (Trent University's Marguerite Xenopoulos and University of Saskatchewan's Amin Elshorbagy). These efforts yielded innovative tools for hydrologic modeling, real-time monitoring, and risk assessment, significantly enhancing Canada's flood preparedness.

A cornerstone of FloodNet's success was its commitment to training highly qualified personnel (HQP), allocating over 72 percent of its budget to students and postdocs. Many graduates from Coulibaly's McMaster lab have secured positions at hydropower giants like Hydro-Québec and Manitoba Hydro, provincial forecasting centers, and Environment Canada, bridging academia and practice.

FloodNet2: Funding, Scope, and the 10 Key Projects

Fast-forward to April 2026, and FloodNet2 emerges with renewed vigor. Coulibaly has garnered $1.395 million from NSERC, $844,430 in cash from industry partners, and $654,000 in in-kind contributions, fueling a four-year push ending in 2030. This phase zeroes in on urban flash floods—a growing menace as intense rainstorms overwhelm city infrastructure. With 80 percent of Canadians living in urban areas prone to rapid inundation, the stakes could not be higher.

The 10 research projects form the backbone of FloodNet2, blending cutting-edge technology with practical application:

• Establishing a Community of Practice to rigorously test and refine tools from phase 1.
• Modernizing probable maximum precipitation (PMP) estimates for critical infrastructure like dams and nuclear plants.
• Developing AI-driven, satellite-enhanced, sensor-based flash flood forecasting and early warning systems.
• Additional initiatives targeting urban hydrology, real-time data assimilation, and probabilistic risk modeling (specifics to be detailed in upcoming announcements).

These projects promise a unified national framework, akin to the U.S. model, to standardize predictions and save billions in future damages.

McMaster University at the Helm: Paulin Coulibaly's Vision

Paulin Coulibaly, PhD from Université Laval and a McMaster professor since 2001, embodies the intersection of academia and real-world impact. His expertise in hydroinformatics—data-driven hydrology methods—has positioned him as a global leader in flood prediction. Coulibaly's lab at McMaster's Department of Civil Engineering and School of Earth, Environment & Society serves as FloodNet's nerve center, fostering interdisciplinary teams that include current students working shoulder-to-shoulder with government and industry experts.

"Climate change is increasing the frequency, intensity, and unpredictability of devastating floods across our country. We need to be much better prepared," Coulibaly stated. He emphasizes training: "Training the future generation of Canadian hydrologists is the key motivation." His decade-long dedication has not only advanced science but also launched careers, with FloodNet alumni integral to Canada's water management landscape.
