Q5. The following information is given: Pressure head at point A: -0.12m; pressure head at point B: -0.05m; The top soil surface is selected as datum. Determine (1) whether the water flow takes place between point A and B (see Figure 2). (2) If water flow exits between A and B, please determine the water flow direction (clearly show the calculation procedures) (2 marks). 0.08m 0.15m B 0.82m Datum Figure 2. Soil profile with point A and B. Q5. The following information is given: Pressure head at point A: -0.12m; pressure head at point B: -0.05m; The top soil surface is selected as datum.
