A nonhydrostatic numerical model was developed and numerical experiments performed on the interaction of an internal solitary wave (ISW) with a sill, for a two-layer fluid with a diffusive interface. Based on the blocking parameter (Br), the flow was classified into three cases: (1) when bottom topography has little influence on the propagation and spatial structure of the ISW (Br<0.5), (2) where the ISW is distorted significantly by the blocking effect of the topography (though no wave breaking occurs, (0.5<Br<0.7), and (3) where the ISW is broken as it encounters and passes over the bottom topography (0.7<Br). The numerical results obtained here are consistent with those obtained in laboratory experiments. The breaking process of the incident ISW whenBr≈0.7 was completely reproduced. Dissipation rate was linearly related to the blocking parameter whenBr<0.7, and the maximum dissipation rate could reach about 34% asBrraised to about 1.0. After that, instead of breaking, more reflection happened. Similarly, breaking induced mixing was also most effective duringBraround 1.0, and can be up to 0.16.
