Subject of research

Main goal of the project is the quantification of the impact of the biological factors on the soil water movement using soil and soil-physical characteristics as soil moisture, stability and water repellency index, sorptivity a soil hydraulic conductivity. In order to analyse spatial organization of the soil moisture and water repellency the attention will be paid on the following organization stages: continuity, anizotrophy, connectivity and convergency. In the case of soils with macropores or water repellency features is it possible to predict the two-domains flow, fingering and other nonstationary effects affecting also spatial soil moisture variability. From this reason it is not possible always use ono-domain modelling of the soil water movement based on the Richards´ equation but it is assumed the use of models based on the percolation theory (applicants from the IH ASCR) and two-domains model S1D Dual (applicants for the FCE CTU).
