Numerical Simulation Study on Wave Runup of Curved Seawall

Using FLUENT software, this paper creates a two-dimensional numerical wave flume and wave creep model based on the
$k-\varepsilon$
turbulence model and the VOF method to track the free surface, uses the boundary condition method to create waves, and uses the sponge layer damping method to dissipate waves, and after verifying the validity of the numerical model, simulates the wave creep process on the slope embankment. The effects of dike top height, relative water depth and different curved surfaces on wave overtopping are analyzed. The results show that the wave runup height increases with the increase of relative water depth and decreases with the increase of the top height of the embankment; the wave runup height on the single-arc wave protection wall is smaller than that on the double-arc wave protection wall.
