Combination Mode of Internal Waves Generated by Surface Wave Propagating over Two Muddy Sea Beds

Figure 7

Growth rate of internal short waves for different density ratios of the right muddy section (𝛾^′′=0.83, 0.78), water depth 𝐻=4 m, mud layer depth ℎ=0.1 m, and density ratio of the left muddy section 𝛾^′=0.83.
