shrinkage limit

shrinkage limit

[′shriŋ·kij ‚lim·ət]
(geology)
That moisture content of a soil below which a decrease in moisture content will not cause a decrease in volume, but above which an increase in moisture will cause an increase in volume.

shrinkage limit

Of a soil, that water content at which a reduction in water content will not cause a decrease in the volume of the soil mass, but an increase in water content will cause an increase in the volume of soil mass.

Based on the assumption that normal shrinkage is linear (McGarry and Malafant 1987), Sharma (1989) proposed that bulk density ([rho]) at any water content (w) greater than the shrinkage limit can be approximated by fitting a linear function using 2 measured pairs of p and w.

If soils dry out more intensely, the residual shrinkage zone from air entry to shrinkage limit shows a smaller soil volume decrease compared with water loss.
