• Description:
  Computational fluid dynamic (CFD) modeling was used to simulate several piles under water wave attack. First, the CFD models were tested at small scale using meshes that were functions of wave geometry (i.e., wave height, wavelength, wave period) to verify that the models could accurately reproduce previously reported experimental data. Once verified, the models were scaled up to typical field scales using the same relative mesh parameters. Maximum bed stress data near the piles were recorded, and a relatively simple parametric model was fit to these data that reproduced modeled results with reasonable accuracy. In addition, a more sophisticated parametric model was developed that reproduced results almost perfectly. This parametric model allows one to use FDOT’s erosion rate testing instruments – the Sediment Erosion Rate Flume (SERF) and the Rotating Erosion Testing Apparatus (RETA) – for wave scour design for the single vertical pile design situation.
