tIn this study, we consider the tanF()2-expansion methodfor the traveling wave solu-tions of the potential KdV equation (pKdV)and the (3 + 1)-dimensional shallow water waveequation (SWWE). We find some traveling wave solutions such as trigonometric func-tion, hyperbolic function, exponential function solutions. Then, we showthe two and threedimensional surfaces for some traveling wave solutions obtained in this study by the Mathematica.
