Numerical Modeling of Local Scour in the Vicinity of Bridge Abutments When Covered with Ice

The occurrence of bridge collapse is frequently attributed to the prevalent erosion in vicinity abutments. Accurate determination maximum scour depth abutments imperative ensure a secure and reliable design. phenomenon local at can exhibit significant variations when compared open-flow conditions, primarily due additional obstacle posed by presence ice cover. Research has demonstrated that more pronounced ice. vertical velocity distribution direct impact on both bed shear stress resulting geometry ice-covered conditions. This study aims analyze effects flow through open channels covered conditions process around semi-circular square using FLOW-3D V 11.2 software. utilization volume fluid (VOF) approach employed for monitoring free surface, while Reynolds averaged Navier-Stokes (RANS) equations RNG k turbulence model are simulating field sediment transport formulated Meyer-Peter Müller were purpose movement particles. numerical simulation results with experimental results. result shows cover its roughness increase studies. also indicate located upstream section These findings demonstrate ability predict under presence.
