Researcher: New stormwater infrastructure is needed for Canadian cities to handle increased urban flooding

Urban flooding is increasingly concerning in Canada, where water drainage systems are at risk of being overwhelmed. Natural watersheds have been greatly altered by construction disturbing the natural ways that water flows from rainfall, across the land and into water bodies. The result is that drainage infrastructure must cope with increased water volumes at both higher speeds and flow rates, as well as deteriorated water quality due to pollutants such as oil and organic waste.
