Results of statistical KS and ANOVA test analysis showed that the model predictions were sensitive to the horizontal eddy viscosity and the Manning roughness. However, considering the balance between the computational cost and the accuracy of the results, both models were capable to adequately replicate the hydrodynamics of the river during the 2013 flood. It was shown that Delft3D-Flow model may require higher grid cell resolution to result in comparably same depth-averaged velocities throughout the study area. The results of this study demonstrated that, with approximately the same averaged grid resolution, MIKE 21 FM resulted in more accurate results with a higher computational cost compared to the Delft3DFlow model. Performance of each model was evaluated by the available historical water levels. MIKE 21FM employs unstructured triangular mesh while Delft3D-Flow model uses curvilinear structured grids. This study investigates the performance of Delft3D-Flow and MIKE 21 FM to simulate the hydrodynamics of the river during the 2013 flood. Channel banks were eroded at various locations, and large gravel bars formed, which could lead to water level changes and accordingly more flooding. Erosion and deposition processes were exacerbated by a catastrophic flood in 2013. This study aims at hydrodynamic modelling of Bow River, which passes through the City of Calgary, Canada.
