Professor-researcher at the National Institute for Scientific Research, Alain Mailhot, in an interview for the programs "Les années lumière" and "QUB Radio" on the management of extreme rains.
Significant floods of water recorded in recent years have caused various devastation and flooding. We can for example remember the precipitation of 160mm of rain in 24 hours in Saguenay in 1996 which caused a catastrophic flood. Moreover, global warming is causing the global intensification and frequency of this extreme precipitation.
As professor-researcher Alain Mailhot mentions during his interviews, it is necessary to adapt to these extreme weather events to reduce our vulnerabilities to these events. To do this, Mr. Mailhot suggests some possible solutions. The first concerns the design of future structures and the adaptation of current structures such as sewer networks, retention basins and dams according to the statistics of extreme precipitation from forecast models. The development of green infrastructure to facilitate water infiltration and therefore reduce runoff is another suggested avenue. Finally, land use planning to allow the installation of these green infrastructures such as green roofs as well as the redefinition of flood zones could also help reduce our vulnerability to these extreme floods.
