Extreme weather conditions can tax urban drainage systems to the max

During a typical Canadian winter, snow accumulation and melt—combined with sudden rainfalls—can lead to bottlenecks in storm drains that can cause flooding.

With that in mind, researchers at UBC’s Okanagan campus have been examining urban stormwater drainage systems, and they too have concerns about the resilience of many urban drainage systems.
A recently published paper from the School of Engineering says existing design methods for urban drainage systems aren’t going far enough to withstand possible catastrophic storms or even unpredictable failures during a moderate storm.
“As engineers, we run simulations of possible catastrophic events, and current systems often do not fare well,” says…
