A comparison between two acknowledged methods and a proposed new one using disturbed soil, for estimating volume change is made, using surface and subsurface samples of alluvial clayey soils (40 - 43%) with different levels of ESP. The values of soil volume change obtained by the proposed method are highly and significantly correlated with those obtained by the other two methods for surface and subsurface samples. Also the values of soil volume changes are calculated in terms of both moisture content and ESP values using a regression equation. Equations with appropriate values for the constants a and b, in the equation Y= a + b x used to inter - transfer results obtained by the different methods, are proposed.
