Fig. 6

Ship velocity and tsunami current in the HDG-normal direction. In a, green and black lines indicate the HDG-normal velocity shown in Fig. 3 (vn) and the apparent sway velocity due to ship yawing in Fig. 5 (vs), respectively. In b, green and red lines indicate the corrected HDG-normal velocity (v = vn − vs) and the simulated tsunami current (vc) shown in Fig. 3b, respectively. Arrows indicate periods where vs is relatively large in a and is effectively corrected in b. Correlation coefficients between v and vc are attached in the same way as in Fig. 3
