Fig. 4. The experimental specific volume of an unlimited clay layer (asterisks) including cracks, 
l (field conditions, Bronswijk's approximation when the layer before drying is composed of unconnected anisotropically shrinking cubes), and clay samples (circles) including cracks, s, and the specific volume of a clay matrix without cracks (solid line), predicted from Chertkov (2000)(2003) using data on 
s, z, and wL (Table 2) for the clay of 0- to 30-cm depths of soil in Sarid, Israel. The inclined straight line is a 1:1 theoretical. Figures near experimental points correspond to the measurement numbers in Tables 3 and 6.
