Lower Fraser River Hydraulic Model Final Report. Prepared by Northwest Hydraulic Consultants and Triton Consultants for Fraser Basin Council. References: 1. 2. 3. 4. 5. 6. 7. Flood levels were developed for five coastal flood scenarios as described in NHC et al. (2014). High flood levels in this reach of the Fraser River are primarily governed by the ocean level and are relatively insensitive to the Fraser River flow (refer to NHC et al., 2014). This map delineates the Fraser River flood potential under Year 2100 conditions, assuming a 1.0 m sea level rise (SLR) and a current 500-year return period flood event. A 500-year return period flood means that, on average, the flood will occur once in 500 years and that there is a one-in-500 chance that the flood levels mapped could be equalled or exceeded in any one year (or that there is about a one-in-10 chance that the flood level mapped could be equalled or exceeded in a period of 50 years). The adopted value for SLR is based on guidelines from Ausenco-Sandwell (2011), and discussions and recommendations from the project s Technical Advisory Group. A freeboard allowance (safety factor) of 0.6 m is included in the flood levels shown. The flood levels are based on water surface profiles simulated using a one- dimensional hydrodynamic model developed by NHC (NHC, 2006 and NHC, 2008). Isolines, showing incremental water levels across the channel and floodplain, were estimated using the model. The model geometry was kept constant at all flows although variations (scour and erosion) may occur during a flood. In the model, some dikes and roadways were raised to confine the flow. The one-dimensional model did not simulate water level variations perpendicular to flow. Channel avulsions or blockages were assumed to be absent. The accuracy of the simulated flood levels is limited by the reliability and magnitude of the flow and water level data used for calibrating the model. LiDAR data surveyed in 2013 was used to create a Digital Elevation Model (DEM) for the City of Vancouver; the DEM surface was edited to remove buildings and temporary features. The maps depict flood levels based on ground conditions at the time of the surveys. The accuracy of the location of a floodplain boundary is limited by the accuracy of the DEM. Changes to the channel, floodplain, and river basin runoff will affect the flood levels and render site-specific information obsolete. Local features such as roads, railways or dikes can restrict flow and locally affect flood levels. Channel obstructions, local storm water, groundwater or tributary streams may also affect flood levels. The flood mapping does not take local features into account. A Qualified Professional must be consulted for site-specific engineering analysis. Flooding from other sources, such as tsunamis or landslide generated waves, should be confirmed with appropriate maps and resources. Industry best practices were followed to generate the flood maps. However, actual flood levels and extents may vary from those shown and Northwest Hydraulic Consultants Ltd. (NHC) does not assume any liability for such variations. Notes:
