On the Dynamics of Two-Dimensional Capillary-Gravity Solitary Waves with a Linear Shear Current
Figure 5
(a) Unstable elevation solitary wave with , , and amplitude-decreasing perturbation is applied, and it finally evolves into a depression wave with some radiations. The plots are shown for from top to bottom; (b) stable large amplitude elevation wave with , , and . 5% amplitude-decreasing perturbation is applied, , 1000, 2000 from top to bottom. The frame is moved with the original propagating speed .
