Water can be absorbed by clay minerals and incorporated into their microstructure. Volume changes in clay particles occur during these processes (water absorption or loss). Clay particles with a high concentration might cause volume variations in soils if moisture levels fluctuate at the same time. The volume changes that occur in heavy soils during shrinking and swelling processes are significant because they are accompanied by soil surface shrinkage and the creation of fissures. Crack formation and dynamics have a significant impact on heavy soil transport mechanisms and, as a result, on their water regime. The results of the examination of the influence of clay content on the influence of clay content on the influence of clay content on the influence of clay content on the influence of clay content on the influence of soil geometric factor, coefficient of linear extensibility (COLE), potential of linear extensibility (PLE), and coefficient of linear extensibility (COLE). The notion that texture has an effect on the value of the volume change potential and the geometric factor, and thus on the degree of volume change distribution on the vertical and horizontal components, was confirmed. According to the hypothesis, the clay soil component has the biggest impact on the volume change potential and the geometric factor value. Field and laboratory measurements are used to get new information. The findings will be utilised as inputs for numerical simulations of heavy soil water regimes.
