Fig. 3: The influence of soil hydraulic parameters on isotope separation.
From: The extent to which soil hydraulics can explain ecohydrological separation
The effect across model simulations of varying soil saturated water content on the average δ2H difference between drainage and a mobile or b immobile soil water as well as the influence of varying soil saturated hydraulic conductivity on the average δ2H difference between drainage and c mobile or d immobile soil water. Differences are show as boxplots for models with high and low immobile fractions (Hf and Lf) and transfer rates (Hω and Lω) as well as for a single porosity column (0f). Each boxplot represents flux and volumetrically weighted averaged differences, with the box spanning upper and lower quartiles, whiskers extending 1.5 times the interquartile range, diamonds as outliers, and black triangles indicating the mean calculated from 10 simulations. Missing boxplots at 0.35 cm3/cm3 in a and b, 0.40 cm3/cm3 in a and b, and 40 cm/day in c and d indicate where HYDRUS-1D model configurations failed to converge.
