Flood Risk Modeling of Halifax Harbour

2.9 metre CGVD28 Flood Scenario - Downtown Halifax

The Nova Scotia Community College's (NSCC) Applied Geomatics Research Group (AGRG) was part of an evacuation analysis undertaken by Dalhousie University & the Marine Environmental Observation Prediction and Response Network (MEOPAR), entitled,“Evacuating the Halifax Peninsula: A Multidisciplinary Analysis and Training to Improve Evacuation from Coastal
Floods”.


The AGRG was tasked to complete the spatial flood analysis and inundation of roads infrastructure to support the evacuation analysis. The analysis required the development of an inventory of major Halifax peninsula roads impacted under various flooding scenarios, and to provide the flood extents for five flooding scenarios.

 

Flooding Scenarios:


The development of this inventory involved the manipulation of spatial roads data provided by the National Road Network, as well as lidar elevation data provided by the Halifax Regional Municipality (HRM) to produce flood depth maps for Halifax. The depth maps and road inventory analysis were produced using a suite of GIS and proprietary modeling tools and software which are critical to the analysis of infrastructure vulnerability under various flood risk scenarios.
