It is very difficult to take an accurate measurement of parameters of the water transfer properties in the soil, although they are important to investigate the hygrothermal characteristics in particular soil under rooftop lawn surface. The hydraulic conductivity, the matrix potential and the diffusion of water vapor in the soil pores express the moisture properties in the soil; they are generally considered as functions of the soil water contents, represented with several parameters. In this study, the procedure to estimate those parameters simultaneously by the inverse solution technique is discussed. Parameter identification method, so-called the inverse solution based on Least Square Technique, was applied to evaporation rates and volumetric water contents selected as the object variables. Results from both experiment and simulation show practical effectiveness and proper accuracy of the procedure presented in this paper.
