The article describes quantification of hydrodynamic load on overflowed bridge deck using 3D numerical simulation. During floods water level in a river channel can reach a lower edge of a bridge deck and bridge deck can be overflowed. Hydrodynamic load is caused by water flow around a bridge deck. Quantification of the load is an important input to assessment of a bridge deck stability. Solution was pursued by using 3D numerical simulation of open channel flow in Flow 3D software. Influence of shape of bridge deck on value of hydrodynamic load was verified for different shapes of bridge deck and different values of inundation ratio and flow velocity. Values of drag coefficient is result of computation. The article provides comparison of 3D numerical simulation with physical experimental testing in Flow 3D and result of 2D numerical simulation in ANSYS Fluent.
