Climate-driven urban flooding is becoming an increasingly critical issue as a result of a multitude of factors, 包括老化的下水道基础设施, urban intensification and flood mitigation design practices that have not stood the test of time. 在多伦多, some sewer and drainage systems are approaching 100 years old, making them unlikely to be able to withstand above average rainfall, 更不用说极端天气了, which have been happening on an increasing frequency in Canada over the last ten years.
Drainage and sewer systems that are unable to mitigate stormwater flow and sewer backup result in urban flooding, an issue that has accounted for nearly $2 billion in average annual property damage claims in Canada between 2009 and 2021.
For municipal agencies looking to mitigate the issue of flooding in their area, a combination of collaboration and technology are key to solving this issue. 2D flood 造型 helps engineers better understand flood risks in their area and enables a comprehensive assessment of potential flood zones. 然而, many agencies run the risk of placing too much reliance on 2D models when the best solution can be found by working with other municipalities tackling the same issue. Confirming a mixture of technology and collaboration will be the key to solving Canada’s growing urban flooding problem.
