AbstractThis paper compares the energy calculations of the potential and kinetic energy, and the power generated by a gravity water wave, using fully nonlinear theory with the corresponding calculations using simple linear theory. To perform these nonlinear calculations a fully nonlinear numerical wavetank model is utilized to generate and propagate monochromatic gravity long-crested waves for an incompressible invicid homogeneous fluid of infinite depth. This model employs a non-orthogonal curvilinear coordinate system, which follows the free surface so the entire fluid domain contributes to the energy calculations at all times and up to the free surface.
