Internal Undular Bores in the Coastal Ocean

Fig. 4 A simulation of the
vKdV equation (13) when
𝛼(𝜏) varies from 1 to −1 as
specified by (23) for the
undular bore initial condition
(25) with U 0 = 6, 𝜏 1 = 5 and
K = 0.3, 𝜏 a = 10 (K𝜏 a = 3);
the top panel is at 𝛼 = 1, the
middle panel is at 𝛼 = 0 and
the bottom panel is at 𝛼 = −1
