“…The idea of full-range equations for friction factor covering all the regimes of wave and wave-current boundary layer was first proposed by Tanaka and Thu (1994). Here the same approach has been followed by specifying the wave boundary layer thickness in the following general form:…”

“…Considering the flow regime, f cw for rough turbulent regime derived by Tanaka and Thu (1994) will be applied. Although it did not include wave reflection criterion on its derivation, however, it is very convenient to use for practical application considering it does not need complex approximation to obtain the solution since it was derived as explicit form.…”

This study is conducted to analyze the effect of coastal structure to depth of closure variation. Analysis on time series bathymetry data has been applied to determine location of depth of closure. The deviation of bathymetry profile changing is also considered. Furthermore, longshore variation of depth of closure is proposed. The hydrodynamic conditions are simulated using Boussinesq model derived by Peregrine (1967). This model is applied considering its applicability to observe non-linear and dispersion phenomenon while wave propagates to the shoreline. The simulation is carried out under regular wave assumption with 20% wave height in deep area is applied as representative wave. The simulation results are obtained in term of surface water level, bottom velocity in x and y direction and current velocity. The result is utilized to calculate maximum bottom velocity just outside boundary layer. To observe sediment movement along the coast, maximum shear stress is calculated under wave-current combined motion. Dimensionless Shields parameter is also assessed. The simulation results are depicted in spatial map. Furthermore, the effect of coastal structure to depth of closure variation is confirmed using hydrodynamic conditions.
