Fig. 9. (a) Unsaturated hydraulic conductivities at each supply pressure head (h) calculated using Wooding's analysis (the values were corrected as regards the soil pressure heads listed in Table 4) and the corresponding optimized hydraulic conductivity functions and (b) soil water retention values of the Dahlem soil from soil cores and optimized bimodal soil water retention curves obtained from three sequential disk infiltrometer experiments. The infiltration experiments were conducted at the same place: the agrometeorological station of the Technical University of Berlin in Berlin-Dahlem (Germany). Additionally, (a) shows unsaturated hydraulic conductivities of the Dahlem soil obtained from laboratory evaporation experiments. Laboratory soil water retention points were incorporated into the optimization processes.
