The oblique reflection of an incident internal solitary wave is investigated using a fully-nonlinear and strongly-dispersive internal wave model. The 3rd order theoretical solution for an internal solitary wave in a two-layer system is used for the incident solitary wave. Two different incident wave amplitude cases are investigated, in which nine and eleven different incident angles are used for the small and large incident amplitude cases respectively. Under both amplitudes, at least for the cases investigated here, relatively smaller incident angles result in Mach reflection while relatively larger incident angles result in regular reflection. Under Mach-like reflection generation of a ‘stem’ is observed for a certain range of incident angles, in addition to the reflected wave. The stem is found to have, in a certain sense, the characteristics of an internal solitary wave, though the maximum stem wave amplitude is less than four times as large as the original incident internal solitary wave. The stem length is confirmed to increase faster for the larger incident wave amplitude. The maximum amplification factor for the small incident wave is the same as in previous studies. However, the maximum amplification factor for the large incident wave is less than that for the small wave. The results of these calculations are compared with those of the corresponding KP theory and it is found that a lower amplification factor may be a significant characteristic of internal solitary waves.

Soliton interactions of the Benney-Luke equation describing shallow water waves are investigated analytically and numerically. An approximate two soliton solution is derived by using a method which combines the Hirota bilinear method and a perturbation method. It is shown numerically that this approximate two soliton solution describes the behavior of two-dimensional soliton interaction of shallow water waves very well. It is shown that critical angles of transitions of soliton interactions are computed analytically from the approximate two soliton solution.

The dynamics of solitary waves in horizontally two-dimensional region is not yet well understood. Recently two-dimensional soliton interaction of
Kadmotsetv-Petviashvili (KP) equation which describes the weakly nonlinear long wave in shallow water system has been theoretically studied (e.g. Kodama
(2010)). It is clarified that the “resonant” interaction which forms Y-shaped triad can be described by exact solution. Li et al. (2011) experimentally studied
the reflection of solitary wave at the wall and verified the theory of KP equation. To investigate more general interaction process, an experiment in wave tank
using two wave makers which are controlled independently is carried out. The wave tank is 4m in length and 3.6 m in width. The depth of the water is about
8cm. The wavemakers, which are piston-type and have board about 1.5m in length, can produce orderly solitary wave which amplitude is 1.0-3.5cm. We
observe newly generated solitary wave due to interaction of original solitary waves which have different amplitude and/or propagation direction. The results are
compared with the aforementioned theory of KP equation.

Solitary waves are typical nonlinear long waves in the ocean. The two-dimensional interaction of solitary waves has been shown to be essentially different from the one-dimensional case and can be related to generation of large amplitude waves (including 'freak waves'). Concerning surface-water waves, Miles (1977) theoretically analyzed interaction of three solitary waves, which is called "resonant interaction" because of the relation among parameters of each wave. Weakly-nonlinear numerical study (Funakoshi, 1980) and fully-nonlinear one (Tanaka, 1993) both clarified the formation of large amplitude wave due to the interaction ("stem" wave) at the wall and its dependency of incident angle. For the case of internal waves, analyses using weakly nonlinear model equations (e.g. Tsuji and Oikawa, 2006) suggest also qualitatively similar results. Therefore, the aim of this study is to investigate the strongly nonlinear interaction of internal solitary waves; especially whether the resonant behavior is found or not. As a result, it is found that the amplified internal wave amplitude becomes about three times as much as the original amplitude. In contrast, a "stem" is not found to occur when the incident wave angle is more than the critical angle, which has been demonstrated in the previous studies.

It is shown that the simplest two-dimensional long wave nonlinear model for the propagation of the rogue waves corresponds to the Kadomtsev-Petviashvili (KP) equation. The mechanism of the rogue wave formation is suggested based on a resonant head-on collision of two plane incidentally non-interacting waves. Corresponding numerical solution of the KP equation is obtained to account for the formation of localized abnormally high amplitude wave. Peculiarities of the solution allows to explain rare but unexpected appearance of the rogue waves. The shape of the steady state of the solution differs from that of the exact two-soliton solution of the KP equation.
