Fig. 7
Capillary radius with air (y = r6) as a function of water content (x = WC) below the residual value (RWC) with exponential and linear equations. Explanation of symbols in the figure, (a) Edosaki soil with initial dry density of 1220 kg m–3 (drying – E_d1, wetting – E_w1) and with initial dry density of 1350 kg m–3 (drying – E_d2, wetting – E_w2); Chiba soil with initial dry density of 1250 kg m–3 (drying – Ch_d1, wetting – Ch_w1) and with initial dry density of 1420 kg m–3 (drying – Ch_d2, wetting – Ch_w2) and (b) Remolded Sandy Colluvium (drying – RSC_d1, wetting – RSC_w1), Remolded Silty Clay (drying – RSC_d2, wetting – RSC_w2), Undisturbed Silty Clay (drying – USC_d1, wetting – USC_w1).
