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).

In cases where there is no flow, the pore pressure at depth below the water surface is:  u = gw d
