Numerical solutions of stationary progressive water waves are obtained through a new method using nonlinear wave equations, where advection equations are satisfied for physical quantities, i.e., surface/interface displacements, velocity, or velocity potential. In the calculation process, the Newton-Raphson method is applied to find convergence solutions. In the present study, the nonlinear wave equations based on a variational principle are adopted as the fundamental equations. Stationary solutions of traveling surface/internal solitary waves are obtained to be compared with the corresponding theoretical solutions, as well as numerical solutions of Euler equations, such that the accuracy of solutions through the wave equations is verified also for large amplitude internal solitary waves with large wave celerity and flatter wave profiles.
