| Abstract: |
| In this paper, we investigate the traveling wave solutions of a small-aspect-ratio wave equation and an integrable evolution equation for surface waves in deep water. By applying the qualitative theory of differential equations, we analyze the phase portraits of the traveling wave systems and obtain the exact explicit representations of solitary wave solutions. |
