 : In the present talk, we derive  a simplified phenomenological  model  of  shallow-water wave propagating mainly in the equatorial ocean regions with  the Coriolis effect  caused by the Earth's rotation. The model equation  which is  analogous to the Green-Naghdi equations with the second-order approximation of the Camassa-Holm scaling captures stronger nonlinear effects than the classical dispersive integrable  equations like the Korteweg-de Vries  and two-component Camassa-Holm system.  The local well-posedness  of the Cauchy problem is then established by the linear transport theory and wave-breaking phenomena is investigated  based  on the method of characteristics and the Riccati-type differential inequality. Finally, the condition of permanent waves is demonstrated by analyzing  competition between the slope of average of horizontal velocity component  and the free surface component.
