| Abstract/Description or Keywords |
This study provides a broad-scale assessment of riparian flood hazard for select streams in North Vancouver through the development of a spatial database containing depths and extents of floodwaters. This database has been developed following the standards outlined for the HAZUS-MH Flood Model and will ultimately be used within this data model to help assess potential disaster loss due to riparian flooding in North Vancouver. Initially 24 creeks and rivers were selected for assessment. A comprehensive data search looking for existing hydrologic and hydraulic data was completed, and ultimately portions of five watercourses were mapped: Capilano River, MacKay Creek, Mosquito Creek, Lynn Creek and the Seymour River. Flood depth maps for various inflows between the 10-year and 200-year flow events in combination with two tidal conditions were created. The maps show that the 200-year flows are generally confined within the main channels of the rivers. Floodplain inundation is observed on MacKay Creek in the vicinity of 1st Avenue and on the Seymour River. |
