Crown-Indigenous Relations and Northern Affairs Canada retained NHC to determine flooding extents for a range of magnitudes along Wabamun and Mink Creeks. The project is located on Paul First Nation approximately 25 km west of Stony Plain, Alberta. The main project tasks included data collection and review, hydrology, hydrographic survey, hydraulic modeling, and flood inundation mapping.
NHC collected bathymetric survey data in spring and summer 2021. LiDAR and the bathymetric survey data were utilized to develop a one-dimensional hydraulic model in HEC-RAS. Photographs from the site and UAV flights were collected to determine site characteristics. Outstanding tasks on the project are scheduled to be completed by the end of 2021.
The results from the study will assist the Paul First Nation assessing flood mitigation, beaver management, land development, climate change impacts, and lake level management.
