Abstract

Wave orbital velocity plays an important roles in many analysis of sediment transport calculation and hydrodynamic model. The accuracy should be ensured to represent the actual conditions. This paper reviewed and compared several approaches for estimating wave orbital velocity under non-breaking irregular waves. There are four methods reviewed in this paper such as Stretching method, Local Fourier Approximation (LFA) method, Fourier decomposition method, and a new proposed method based on the Kaczmarek and Ostrowski (Kaczmarek and Ostrowski, 1996) by adding the correction coefficient factor (αc) with value of 4.35. Those method has been examined and compared through both experimental data and the estimation model. The proposed method gave the best agreement among other methods with smallest RMSE value. The proposed method can be used to estimate wave orbital velocity under non-breaking irregular waves with free surface elevation datas as an input in practical application.
