FIG. 8. Water content variability profile [CV()] and coefficients of variability of the horizontal component of the velocity field profile [CV(v_z)] and the horizontal component of the velocity field profile [CV(v_h)] 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).
