Difference (psi) = [measured pressure

Measured pressure are hourly averages
of 1-minute sampling data; see Appendix D for 1-minute sampling data
Simulated pressure (psi) = [simulated
total head (ft) - elevation of land surface (ft)] / 2.31
Elevation of land surface = 42.81
ft
Difference (psi) = [measured pressure
(psi) - simulated pressure (psi)]; ABS Diff = absolute value of difference
