The paper considers the application of the scheme based on linear combination of the Upwind and Standard Leapfrog difference schemes with weight coefficients obtained by minimizing the approximation error. The proposed difference scheme has shown its effectiveness in solving diffusion-convection problems in the range of grid Peclet numbers 2 ≥ Pe ≥ 20, which allows us to apply this class of schemes for the numerical solution of computational Oceanology problems. The problem of soil dumping was considered as a practical example of application of the proposed schemes.
