phenomena that evolve over space and time, and their However, since the turn of the century, scientific literature consequences will depend as much on the evolution of on the issue of vulnerability in flood-prone areas has the climate as on that of the demographic landscape emerged, particularly in Quebec. [...] However, the significant anthropization (transformation by human activity) of the territory over the years, including the creation and expansion of the Chambly Canal, has changed the water level in Lake Champlain and the natural flow of the Richelieu River. [...] The study found that changes in the hydrology of Lake Champlain and the widening of the Chambly Canal at the beginning of the 1970s caused irregularities in the flow time series that overlapped that period and affected the results. [...] 2.3.4 Quality, Reliability and Scope of Maps The precision and accuracy of flood hazard maps depends heavily on the quality of the data used and the methods selected throughout the map production process. [...] In addition to estimating the economic, social and environmental impacts according to several levels of flooding, this project proposes to map the loss of access to the road network according to different flooding scenarios, which refines the analysis of the sensitivity related to the accessibility of infrastructure (Mathieu Roy, personal communication, March 26, 2021).
