Abstract
In this paper, a three-dimensional numerical model using the Weighted Essentially Non-Oscillatory (WENO) scheme is developed. In the model, the Cartesian coordinate system was adopted, and the Fractional Area/Volume Obstacle Representation (FAVOR) method was introduced into the governing equations. The Highly Simplified MAC (HSMAC) method on the collocated grid system was employed in order to solve the Poison's equation of anomaly pressure. The model was verified against experimental data of flows around a submerged spur-dike on flat fixed bed and on fixed bed with local scour. By comparing the simulated results with the experimental data, the model was found to reproduce the flows around a submerged spur-dike with sufficient accuracy.
