In this paper, generalized 2D shallow sea dynamic equations in movable curvilinear co‐ordinates are derived. Through a differential co‐ordinate transformation a self‐adaptive grid is proposed to treat a continuously deforming lateral boundary and a kinematical boundary condition is adopted. The self‐adaptive grid method (SAM) is used to simulate numerically the storm surge flooding in the Bohai Sea on 23 April 1969, which was one of the largest storm surge inundations in China.
