Fig. 2. Contours of the simulated pressure head, , in a vertical cross-section of the soil (parallel to the x₁–x₂ plane at x₃ = 0.32 m) at the end of an irrigation event. Results are depicted for both the sandy (a) and the clayey (b) soils for Q = 2 l/h. The exterior contour corresponds to = -1 and -9.3 m of water for (a) and (b), respectively, and the corresponding contour increments are 0.02 and 0.5 m of water, respectively.
