Abstract

Soil volume changes of heavy soils due to soil water content change are followed by their volume changes in the process of its shrinkage and swelling. Values of soil volume changes depend on the type and on the content of clay minerals and on soil water content as well. Content of clay minerals is usually stable at the site, but soil water content is changing, depending on meteorological and hydrological conditions. Soil volume changes are performing in both – horizontal and vertical directions. Horizontal deformation of soil creates soil cracks and changes of their dimensions, vertical deformations lead to soil surface level changes. At a given time soil water content W depends on the thickness of the vadose zone layer Δz of soil, i.e. ΔW = F (Δz). The article presents results of integral soil water content calculation based on the above mentioned relationship. Vertical changes of soil surface level were measured in the field, near the site Senné (East Slovakia Lowland).
