Analyzing an approximate solution to a quasilinear parabolic-hyperbolic problem.

The article presents a study which investigates the approximate solution to quasilinear parabolic-hyperbolic problem. The study used an initial-boundary-value problem for quasilinear system in four differential equations to represent the mathematical model of interrelated processes of soil mass and heat and moisture transfer being analyzed. Study has presented an algorithm for the problem's approximate solution.
