The proposed research is focused on detection and evaluation of soil substrate structural changes of selected anthropogenic soil systems. Experimental sites on extensive green roof and interlocking grass pavers fully equipped for continuous hydrometeorological and hydropedological monitoring will provide detailed information about water and heat regime of soil systems. Internal soil structure of systems studied will be visualized and characterized on undisturbed samples non-invasively by means of X-ray computed tomography. The tomographic images will be used for qualitative and quantitative analysis of soil heterogeneity and structure temporal changes caused by atmospheric forcing and plant activity. The acquired experimental data of computed tomography will be combined with numerical model to identify how water and heat dynamics in anthropogenic soil systems are affected by soil structural development.
