Based on the σ-coordinate transformation to fit the complicated boundary,the VOF to track the moving free surface and the SIMPLE algorithm,this paper proposes a vertical 2D unsteady flow and suspended material distribution model.

Try to establish a three-dimensional ice-water model based on the boundary-fitting curvilinear coordinate system adopted in the horizontal x-y plane andσ-coordinate transformation in the vertical direction.

The σ coordinate transformation was used in the vertical so that the free surface and bottom boundary conditions could be precisely implemented.

Based on the research of former researchers, and the two-dimensional tide diffuse formula from Cartesian Coordinates , by using σ coordinate transformation technique to transform the tide diffuse equations from Cartesian .
