A four-element list containing four vectors: depth = depth,
sigmaZ.eff = effective vertical stress, sigmaZ.total = total vertical
stress, and u = pore water pressure
Arguments
gamma
= vector of unit weights (pcf or kN/m^3)
thk
= vector of layer thicknesses (ft or m)
depth
= vector of layer bottom depths (ft or m)
zw
= depth of groundwater table (ft or m)
zout
= desired depths of output (ft or m): defaults to critical
locations in the profile (the top and bottom of the profile, layer
interfaces, and the groundwater table) [recommended]
gammaW
= unit weight of water (default = 62.4 pcf for English units;
9.81 kN/m^3 for metric units)
metric
= logical variable: TRUE (for metric units) or FALSE (for
English units)
