    Abstract

    <p>Field experiments and additional measurements on undisturbed soil samples in the laboratory were done to investigate the variability of the parameters used in modelling soil moisture conditions.</p><p>The conditions of soil water control the amount of moisture available for the plant cover, crop production, transport of contamination in the unsaturated zone, and are thus of interest for the study of processes of soil erosion and mass movement and for land evaluation.</p><p>Attention was paid to hydraulic soil characteristics as well as to plant-soil parameters for determining actual evapotranspiration.</p><p>The research mainly concerned loamy and silty soils in the Ardèche drainage basin.</p><p>The results demonstrate the need for models in which the variability of the hydraulic characteristics can be reduced to basic parameters. For land evaluation it is important for such parameters to be related to physiographic properties that can be mapped easily.</p>
