摘要: This paper deals with numerical algorithms for solving elliptic-parabolic problems. An example of such problem is given by the Richards equation modeling saturated-unsaturated water flow in porous media. We consider a linear model and investigate convergence two finite-volume schemes. The first one uses implicit approximation whole domain, second scheme constructed using splitting method. Results experiments are also given.
