FIG. 7. Averaged water content () profile, averaged horizontal component of the velocity field (v_h) profile, and averaged vertical component of the velocity field (v_z) profile after 0.5 and 7 d for Collar Boundary Conditions 1 (continuous lines) and 2 (dashed lines). Line colors refer to different root or soil parameterization: reference (black), xylem conductivity multiplied by 10 (blue), radial conductivity multiplied by 10 (green), and soil hydraulic conductivity multiplied by 10 (red).
