1. For a soil in which the soil moisture conditions are at equilibrium (there is no upward or downward flow) and a water table at a depth of 3.5 m below the soil surface, draw a diagram showing the variation with depth of the matric, gravitational, and hydraulic heads. Use Figure 1 below as your guide. You will need to draw three lines, one for W., Um and h. Only extend the lines to the water table. Remember, where there is no flow, that means hydraulic head is equal throughout the profile.
