The main object of this thesis is to solve (1+1)-Dimensional Dispersive Long Wave Equations numerically, which play important roles in nonlinear physics, that describe the evolution of horizontal velocity component of water waves of height propagating in both directions in an infinite narrow channel of finite constant depth. We used Successive approximation method, Modified successive approximation method, Variational iteration method, Homotopy perturbation method, Variational homotopy perturbation method and Homotopy analysis method. Mathematica software has been used for computations.
