Resumen

Water potential is the energy of water in a soil resulting from the different forces acting upon it. Water potential is a measure of the capacity of the soil to hold water in its pores. Experimental results show that the soil water retention capacity tends to reduce with increasing temperature. The paper presents a formulation developed using concepts of thermodynamics of adsorption that relate changes in the energy status of water in soil with changes in temperature. Experimental results of water retention capacity obtained on compacted samples of an expansive clay have been analysed using this approach and that deduced using the capillary model (i.e. considering the changes in the surface tension of water by temperature increments). The results suggest that mechanisms other than the change in the surface tension affect the retention capacity of water in soils as temperature increases.
