| Abstract/Description or Keywords | In late November 2009, a series of frontal systems hit coastal British Columbia. Flood warnings were issued across Vancouver Island as several rivers experienced very high flows. The worst flooding occurred in the Cowichan Valley on Friday, November 20. Following more than a week of rain, the Cowichan and Koksilah Rivers and several creeks overflowed their banks. Over 50 home were flooded in North Cowichan and the City of Duncan; dozens of homes were flooded “up to the doorknobs”. Residents were evacuated, roads and schools were flooded and closed, and property damage was extensive. Between November 15 and 26, the MNC raised dikes and filled gaps and low spots in certain critical areas near the flooded areas around Lakes Road. On November 26th, 2009 Northwest Hydraulic Consultants (NHC) was retained to complete an assessment of the November 20th flooding event. The assessment includes data collection and surveying of high water marks, running of the previously developed MIKEFlood model to simulate the 2009 flood, assessing the value of the temporary “no-post” barrier instalment on Lakes Road, and to provide recommendations based on the assessment. This report outlines our methodology and findings. |
