If there is a layer of sand (lower layer) under artesian pressure (causes upward flow), calculate the excavation height H so that a negative effective stress is not generated at point A and therefore the heaving of the soil at that point. Use a unit weight of water w of 62.43 lb/ft3. Note: In this example we make a similarity with the permeameter with upward flow, therefore, H1=0 since from the bottom of the excavation (Na) upwards it remains dry (pumping is done), H2= 20ft-H, h=12ft-H2.
