✦ Synopsis

A method for the determination of the heat flux density and the contact coefficient at the surface of a solid body, porous or non-porous, is described. A block of an appropriate material at a uniform temperature is placed on the soil surface and the temperature of the contact plane is recorded. If the initial temperature of the block and its thermal constants are known, the soil heat flux can be calculated. If the soil temperatures at a few shallow depths are measured, the thermal conductivity and the heat capacity of the soil can be calculated separately.

The application of the method is demonstrated by laboratory experiments on soils as well as by experiments in the field.
