Reflection of an obliquely incident internal solitary wave by a vertical wall in a stratified fluid is studied numerically. We employ two different types of equations for the analysis, that is, the equation for incompressible ideal fluids and the Modified Kadomtsev-Petviashvili (MKP) equation derived from the former equation under the assumption of small wave amplitude, small incident angle, large horizontal lengthscale of variation, and the condition for stratification profile specified in the main text, According to the numerical results of the MKP equation, the reflection pattern approaches that of normal reflection in comparison with analyses of Kadomtsev-Petviashvili (KP) equation as the wave amplitude increases.
