Abstract
The present article investigates the effect of Coriolis constant on the solution of the Geophysical Korteweg-de Vries (gKdV) equation. As such, the Homotopy Perturbation Method (HPM) has been applied here for solving the nonlinear gKdV equation. Present results are compared with existing results that are available in the literature and they are found to be in good agreement. Then the Coriolis term has been considered in terms of the interval to form interval Geophysical Korteweg-de Vries (IgKdV) equation. IgKdV equation has been solved by HPM to analyse the effect of Coriolis. From this analysis, it has been concluded that the constant of Coriolis is directly proportional to wave height and inversely proportional to wavelength. The presence of the Coriolis term in gKdV equation has a remarkable change in the shape of the solution.
