Recently, in International Journal of Numerical Methods for Heat and Fluid Flow, Liu (2023), Khuri (2023) andLi et al. (2022) have done some excellent work on the oceanic shallow water, respectively, via a (3þ1)-dimensional generalized shallow water wave equation in an ocean or simulating the weather, a (2þ1)-dimensional Korteweg-de Vries equation for the shallow water waves and a (2þ1)-dimensional Broer-Kaup-Kupershmidt system modeling the nonlinear and dispersive long gravity waves in the shallow water of uniform depth.Getting enthusiastic from Liu (2023), Khuri ( 2023) and Li et al. (2022), this Letter designs to symbolically compute a (2þ1)-dimensional generalized dispersive long-wave system modeling certain dispersive and nonlinear long gravity waves in two directions, horizontally, on the shallow water of an ocean (Gao et al., 2022b(Gao et al., , 2023a(Gao et al., , 2021b(Gao et al., , 2021c(Gao et al., , 2020, i.e.:Letter to the Editor 3801
