Summary:•A mathematical model that determines the shallow subsoil temperature is presented.•Influence of the parameters involved are analyzed.•Several thermal zones and their properties in the shallow subsoil are defined. This paper presents a mathematical model that related the time, depth, temperature and thermal diffusivity of the ground one another, and analyzes their implications and importance in the design of geothermal facilities, and in particular in determining the apparent thermal diffusivity of the subsoil.
