The graphs on the left-hand side have been transposed from the original data on the right-hand side for
clarity Smith, 1995 . All the graphs in Fig. 1 have been drawn at the same scale to enable a visual comparison. Water retention data from Smith 1995 has been superimposed on the x-axis so that an initial interpretation of the PSS values with respect to available water capacity criteria can be made. As the matric potential at a given water content depends upon the compaction level Larson and Gupta, 1980 , three values of matric potential, those corresponding to wilting point 1500 kPa and field capacity 10 kPa , are given in the graphs corresponding to the lowest and highest bulk densities WP and FCL and FCH, respectively . Only one water content is presented for
WP since the changes in water content at WP for different levels of compaction were
too small to be represented on the graphs. It should also be pointed out that the PSS
readings were not carried out on soils dried under tension during the determination of
the water retention characteristic. Gravimetric water content has been used because
volumetric water content or matric potential may change during penetration due to
particle rearrangement whereas gravimetric water content remains constant
