Abstract
This study assessed the lateral and vertical variability of the Atterberg indices within one soil map delineation and inferred the variability of two additional delineations of the Dalhousie association (Brandon series). The data showed that Atterberg indices were highly variable with the liquid limit varying from 33 to 51% for samples from one transect line. This variation was composed of spatial variation in both lateral and vertical directions. Much of the variation in liquid limit was related to the amount of fine material (< 0.05 mm) in this soil, generally considered to be very uniform. Analyses of liquid limits from fewer samples were used to infer variability of two additional delineations. When Atterberg indices for specific depths were used different engineering classifications resulted from that given from mean values for the pedon or map unit. Key words: Atterberg indices, variability, transect, sampling confidence
