Numerical and computer modeling for coupling surface and ground flows

The work relates to mathematical modeling and numerical study of the problem of interaction in the watershed of surface water and groundwater flow in the hydrodynamic and kinematic approximations. Built semidiscretized of depth flow formulation initial and boundary variational problems, which were solved with the use of projection-grid schemes of the finite element method. For discretization problems at the time was used by one-step recurrent scheme. The stability and convergence constructed projection schemes were research.
