In this paper, solutions of a set of coupled nonlinear shallow water wave equations are solved based on the analytical method, and the results are discussed. The behavior of the equation solution un-der different parameters is studied. We concluded that the dispersion coefficient can significantly affect the dynamics of the shallow water wave. Based on the equations given in this paper, some ex-tended applications under special parameters are discussed. The result presented in this paper may give insights to the relevant studies of the shallow water wave equation.
