Improving Flood Risk Evaluation through Cross-Sector Sharing of Richer Data
Canadian Water Network, Insurance Bureau of Canada
Large-scale flood risk models used by Canada’s insurance sector currently use low-resolution topographic data as inputs, and also give limited consideration to flood mitigation infrastructure or defense measures that have been implemented by Canadian municipalities. In a comparative study undertaken by Canadian Water Network and the Insurance Bureau of Canada, incorporating higher resolution topographic data and flood defense measures in these models created a clearer picture that can significantly reduce the level of uncertainty in the resultant flood hazard maps.
