Fig. 2. Degree of saturation in macropores simulated by MACRO and given by the analytical solution (Germann, 1985). Two cases are shown: (i) 24-h pulse at 1-m depth and (ii) 3-h pulse at 0.5 m depth. I_ma = 2 mm h^–1, K_s(ma) = 10 mm h^–1, _ma = 0.1 m³ m^–3, _mi = _b = 0.4 m³ m^–3, n* = 2 for both cases.
