New Flood Risk Management Study Findings Reported from University of Quebec Trois-Rivieres [Spatiotemporal Variability of Fall Daily Maximum Flows In Southern Quebec (Canada) From 1930 To 2018]: Risk Management – Flood Risk Management

2024 MAR 14 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- Current study results on Risk Management - Flood Risk Management have been published. According to news originating from Trois-Rivieres, Canada, by NewsRx editors, the research stated, “Quebec is experiencing a significant increase in summer and fall temperatures and rainfall. This study compares the spatiotemporal variability of maximum daily flows generated by rainfall during the fall season (September-December) in relation to this climatic change and physiographic and land use factors.”

Financial support for this research came from Natural Sciences and Engineering Research Council of Canada (NSERC).

Our news journalists obtained a quote from the research from the University of Quebec Trois-Rivieres, “Analysis of the spatial variability of these maximum flows measured from 1930 to 2018 in 17 watersheds revealed that the magnitude of flows is approximately twice as low on the north shore as it is on the south shore south of 47 degrees N. This difference is explained by three main factors: wetlands (negative correlation) and agricultural (positive correlation) surface area, and summer-fall total precipitation (positive correlation). As for the temporal variability of flows, the different Mann-Kendall statistical tests showed a significant increase in flows due to increased rainfall. The increase of flows was more widespread on the north shore than on the south because the storage capacity of wetlands and other water bodies does not change over time to store excess rainfall. On the south shore, the increase in flows over time is limited due to the significant reduction in agricultural areas since the modernization of agriculture.”

According to the news editors, the research concluded: “This reduction favored infiltration to the detriment of runoff.”
