The depth of closure in Sendai Port is estimated us ing 10 years bathymetry data and proposed as a longshore variation. The hydrodynamic condition is s mulated using Boussinesq equation (Peregrine, 1967) which was modified by applying long wave theo ry. Using wave data from 1991 to 2003, 20% wave height in deep areas is applied as a represent ative wave. From the modeling, bottom velocities in  the x and y directions are obtained. The result is used to cal cul te the maximum bottom velocities just outside the boundary layer. The effect of wave refl ection is observed using the velocity distribution and maximum bottom shear stress. By integrating the vel ocities in the x and y directions, the area that is influenced by reflected waves can be observed. The results are depicted as a spatial map. The longshor e variation of the depth of closure is overlaid on th e results to confirm the influence of wave reflecti on for its variation.
