The paper presents the results of measurements of shrinkage characteristic for alluvial clay soils from the Delta of Vistula River. Measurements were conducted on undisturbed soil aggregates using ‘so-called’ saran resin method. Five following shrinkage characteristic models were fitted to measured data: four segment analytical model, combined exponential-linear model, general soil volume changes equation, three straight lines model and logistic model. The comparison of different models depending on coordinate system as well as advantages and disadvantages of various models are discussed.
