The article deals with modeling the dynamics of the water regime of soil irrigation systems. The model takes into account the mass of pollutants entering surface waters. Modeling the dynamics of soil moisture reserves and ground water level is considered separately for areas with hydromorphic and automorphic modes. The relationship between drainage outflow and ground water level is proposed.
