英文摘要	This paper proposes a method for modelling heat dynamics in soil, which is integrated into deterministic hydrological model "Hydrograph". The method is based on several techniques that simplify the differential equation of heat transfer in soil profile and results in conversion of the system of differential equations to a system of linear algebraic equations without loss of quality of modelling results. Also the approaches used to estimate thermal conductivity and heat transfer of calculated soil layers in the conditions of soil freezing-thawing and variable humidity are described in detail. Physical properties of the materials composing the soil profile, such as density, porosity, thermal conductivity and thermal capacity, the maximum water holding capacity, are used as the model parameters. On the basis of observational data such properties can be generalized and systematized for soil profiles characteristic of major landscapes and used in catchments with similar conditions of runoff formation without the use of calibration methods. Modelling results of soil temperature at depths of 20, 40, 80 and 160 cm at one of the objects of the Kolyma water balance station confirm the effectiveness of the proposed method.
