Soil Mechanics for Unsaturated Soils
The gravitational head distribution in the a-direction is zero at point A (i.e., datum)
, and increases linearly to a gravitational head of (H cos2a) at ground surface.
The pore- water pressure head at a point in the a-direction must be negative and
...

2.7 Pressure head Engineers often refer to pressure in terms of metres of water
rather than as a pressure in kN/m2. So, referring to the pressure calculation in the
box, instead of saying the pressure is 29.43 kN/m2 they will say the pressure is 3
