We help our clients better understand and manage flood risks through custom solutions adapted to their needs.



E-NUNDATION is a web-based platform for dynamic and predictive flood risk mapping. This tool assesses the impacts of floods on people, buildings and critical infrastructure. 


E-NUNDATION is not limited to the simulation of flood hazard, generally characterized by the extent of the flooded area and the depth of flooding. The tool is unique in that it assesses the overall RISK by integrating the exposure of vulnerable elements to flood hazard. 


E-NUNDATION enables the characterization of the vulnerability of issues present in flood-prone areas and their levels of exposure to this hazard. The vulnerable elements are the population, buildings, critical infrastructure and the road network.

Flood risk analysis and management tool


E-NUNDATION calculates human risk by combining the vulnerability of the population, buildings and infrastructure with their level of exposure to a hazard. It therefore facilitates better decision-making in the event of a crisis. 


In collaboration with provincial and local authorities, the tool's functionalities were tested on the Yamaska, Richelieu and Petite Nation rivers in Quebec. These analyses made it possible to quantify the risks and develop a variety of scenarios. The tool has also been tested on real cases, particularly during the floods of spring 2017. This use in real-life situations made it possible to refine and enhance the solutions.


E-NUNDATION offers its users a complete risk assessment, adapted to the various stages of the crisis management process.
