Fig. 2. Examples of simultaneously measured shrinkage (ShC) and water retention (WRC) curves with the fitted XP equations, for Cambisols with (a) 17% and (b) 14% of clay, Vertisols with (c) 46% and (d) 51% of clay, and Fluvisols with (e) 8.5% and (f) 42% of clay. Abscissa: gravimetric water content W. Ordinates: specific bulk volume V (solid line), fitted XP model (dashed line), saturation line (dotted line) and suction h (black dots).
