	abstract = {The shrinkage and swelling phenomena of certain clay soils cause differential settlement manifested by disorders that affect mainly the individual frame. The objective of this research was to create a map related to these phenomena especially in the area of Algeria
N{\textquoteright}gaous (figure 1). The approach of the study is primarily based firstly on the interpretation
of a geological map at a scale 1 : 50 000 and on the other part from existing literature and
observations on a synthesis of a large number of geotechnical information to determine
susceptibility to the phenomenon of clay or marl formations. This approach consisted in the
establishment of a synthetic departmental mapping of these formations that have been
identified from a hierarchy as to their susceptibility according to the shrinkage and swelling
phenomenon. This classification was established on the basis of three quantifiable main
features: the dominant lithology of formations, the mineralogical composition of their clay
fraction (proportion of swelling minerals) and geotechnical behavior (primarily assessed from the blue value and the plasticity index).
Key words: marl, smectite, shrinkage and swelling, natural risk, geotechnical mapping,},
