Correction of the water retention curve
after shrinkage
In order to consider the shrinkage effect on
the water retention curve, the vertical
shrinkage was used to correct the volumetric
water content at each matric potential.
Additionally, the structural changes caused
by shrinkage were expressed by differences
in water content (dq) with and without
consideration of shrinkage, in relation to
the volumetric water content at saturation
as follows:
