The basic governing equations and boundary conditions are deduced in general curvilinear coordinates using natural variable-density turbulence model which describes a two-phase flow with sediment. A new 27-point three-dimensional finite analytic discretization scheme and velocity formula for non-uniform bed material are applied to the calculation of the float open caisson in construction period.
