The power generated by the MEH at t

The power generated by the MEH at the observation points No. 1, 2, and 3 (see Figure 6) can be calculated with Equations (1)–(4), as well for both the scouring-free and scouring pier models. Figure 13 shows the generated power for the two models and the first three modes. Note that the power is presented in a relative manner with respect to the maximum power in the same model and the same mode. As expected, the 1st mode generates the most power in the y-direction at all three observation points as it is a longitudinal bending mode; the 2nd mode generates in the y-direction at observation points No. 1 and 3 as it is a torsion mode; the 3rd mode generates in the x-direction at all three observation points as it is a lateral bending mode. Little power is generated in the z-direction (vertical direction) for all modes.
