Anastase.Pore Water Pressure
Pore Water Pressure (PWP)  is the product of the uplift defined by the depth of the water table,h_U, and the specific weight (or unit weight) of water, gamma_W. Generally, PWP is a measure of the pressure of groundwater held within a soil or rock, in gaps between particles (pores), relative to atmospheric pressure. PWP is measured in piezometers (u).
