The stochastic-deterministic approach to modeling of the 
Saffman-Taylor hydrodynamic instability in filtration of mixing 
fluids in a porous medium is considered. The numerical model is used 
to study the dynamics of development of the instability in displacement 
of a more viscous fluid by a less viscous one in uniformly and nonuniformly 
permeable media. Results of the modeling are compared to experimental data.
