| Abstract/Description or Keywords | In September 2005, the Fraser Basin Council (FBC) retained Northwest Hydraulic Consultants Ltd. (nhc) to undertake a program of one-dimensional hydraulic modeling on the lower Fraser River using the MIKE 11 software developed by Danish Hydraulic Institute. The study area includes the lower Fraser River from the mouth of the Harrison River to the Strait of Georgia, encompassing the North, Middle and South Arms, including Canoe Pass, as well as Pitt River to Pitt Lake inlet. The overall objective was to generate an up-to-date design flood profile based on the following two scenarios: • The 1894 Fraser River freshet flood combined with spring high tide conditions (Fraser freshet profile). • The 1 in 200-year winter storm surge flood with winter high tide conditions combined with a Fraser River winter flow (the winter storm surge profile). The modeled flood profile in 2006 is higher than the estimates that were made in 1969, which have been used as a basis to rehabilitate lower Fraser River dikes under the Fraser River Flood Control Program. The results from this study show that widespread dike overtopping and dike failures would occur throughout the region in the event of a re-occurrence of the 1894 flood of record. |
