This paper describest he mechanism of internalw ave breaking and its effect on the occurrence of residual currents when internal waves break over a uniform mild slope, PIV technique was applied to visualize flow field around the area where internal waves break and run up over a slope. PIV analysise nabled us to compute residual currents which revealed that undertow appears below the interface. Numerical computation was carried out using two-dimensional non-hydrostatic LES model. From the comparisons with laboratory experiment results numerical computations were confirmed to be successfully conducted with good agreements on residual currents. A bore was found from numerical computation results to have a tail which provides baroclinic energy and enhances the occurrence of down-draft
