| A theoretical analysis was done of evaporation for a bare soil and the second and third stages based on a stationary model of consistent heat and water transfer in the system soil- atmosphere (subsurface layer). The effect of thermal, hydrophysical soil properties and meteorological elements was investigated on evaporation intensity and thickness of a dried layer. It was shown that hydraulic conductivity was of decisive value. A boundary condition at the soil surface is found which reflects the peculiarities of water exchange between soil and air media at the stages under consideration. The calculations were performed for five wide-spread soil types. |
