A CONTRIBUTION TO THE STUDY OF THE WATER AND ENERGY BALANCES OF AN IRRIGATED SOIL-PROFILE - A - HEAT-FLUX ESTIMATES

In this paper, an attempt is made to estimate heat flux densities acco rding to various methods for a wet and a dry soil profile. Primary dat a are soil temperature measurements in various depths (2, 5, 10, 20, 5 0 cm). Data concerning the soil texture and composition as well as dat a referring to the soil moisture profile for the selected days of this study are also available. Estimates of heat flux densities obtained t hrough the various methods used are compared with actual heat flux den sities, as these are measured at the depths of 2 and 10 cm into the so il profile. The comparison has been encouraging and therefore heat flu x densities calculation methods may be used for following heat flow in to the soil profile. (C) 1998 Elsevier Science B.V.
