This knowledge allows us to direct land use away from areas of risk – areas that could be inundated with floodwaters, potentially trapping people from escaping from a flooded area and/or damaging private property and public infrastructure.

Flood plains and inundation maps are determined by gathering, analyzing and synthesizing together all the information in a flood study. This study combines hydrology and water level information (generated by the hydraulic model) with topographical information and GIS processing. Together these determine the spatial extent of a flood plain (i.e. an inundation map).

Inundation maps have a variety of uses, including Emergency Preparedness and Response Plans (EPRPs), mitigation planning, and consequence/damage assessment. Municipalities also use floodplain mapping, as it’s a vital part of their official plans and zoning by-laws. These laws, in turn, guide future development in their respective municipalities. In addition, consequence assessment studies utilize inundation boundaries to identify and quantify the potential consequences of dam failure or other incidents.

While the consequence assessment is compiled for multiple flood scenarios within the EPRP context, inundation mapping alone can help dam owners and emergency management authorities identify critical infrastructure and population-at-risk sites. These, in turn, will potentially require protective measures, warnings and/or evacuation planning.
