MODFLOW 6 includes an observation utility (OBS) which is used to output the computed head, drawdown, and/or flow at specific cells at all output times.
GMS includes additional observation features beyond what comes with MODFLOW 6, including observations at arbitrary locations and times, comparison of observed and computed values, whisker plots, and other plots. This functionality is done with the help of utility programs that come with PEST, and is very similar to the observation functionality GMS provides for MODFLOW-USG. GMS prepares the input files needed by the PEST utilities to determine the computed values from the model solution. For more information about using PEST with MODFLOW-USG, refer to the “MODFLOW-USG – Calibration” tutorial.
PEST can be used for observations and calibration. This tutorial only covers observations. This tutorial will convert an existing MODFLOW-USG simulation that uses PEST observations to a MODFLOW 6 simulation with PEST observations.
