Pedotransfer function for calculating the potential of volume changes in soils

Abstract

The volume changes in the soils are manifested both by the formation of cracks and by the vertical movement of the soil surface. Both of these could be generally negative for engineering constructions. The Coefficient of Linear Extensibility (COLE) is used to quantify volume changes. In this work a pedotransfer function was designed to calculate the COLE potential. Calculation is based on the texture of the soil. This function was designed on the basis of 169 samples of soil samples taken at 11 locations in the East Slovak lowland.
