The role of natural infrastructures in flood prevention within the Montreal metropolitan
Abundant precipitation and subsequent flooding in southern Quebec have shown the limits of urban infrastructure with respect to managing run-off.
Natural infrastructure, especially wetlands, buffer against run-off and play an important role in reducing water treatment costs and in preventing flooding.
However, little information is available on hydraulic fluxes and an ecosystem’s capacity for water retention.
This information is essential for planning and developing a region’s green and blue corridors, as well as prioritizing conservation and restoration efforts that improve water retention and flood prevention.
Model hydraulic fluxes in the Greater Montreal region and evaluate the buffering effect of different ecosystems against run-off.
Modeling of water retention at the site level (wetlands and woodlands).
Create a map of the importance of each ecosystem for water retention and flood prevention to establish conservation and restoration priorities.
