Abstract
Meteorologicaol bservationand measuremento fheat and moisture in soil are carried out in an experimentalf ield at United Arab Emirates (U. A. E.) T. he purpose of this experiment is to make a model of heat and moisture transfer in soils for saving the irrigation water in arid region.The movement of water vapor in soils is evaluated by the experimental technique using thermo-hygro meter, which is developed by authors. This technique is useful for the monitoring of evaporation-drying process of soil after irrigation. The characteristics of temperature, humidity and water vapor density profile in soils are similar to those observed by indoor experiments on the evaporation from sand layer under diurnal climate variation.
