where T = time factor from Table 8.2 (dimensionless)
t = time since the application of the load to the in situ saturated cohesive or organic soil layer.
The load is assumed to be applied instantaneously.
cv = coefficient of consolidation from laboratory testing (ft2/day or m2/day)
Hdr = height of the drainage path (ft or m). If water can drain out through the top and bottom of the
cohesive soil layer (double drainage), then Hdr = 1/2Ho, where Ho = initial thickness of the cohesive
soil layer. An example of double drainage would be if there are sand layers located on top
