Given the observation data presented below for the system that you have been building MODFLOW files for in Unit 8 in ex4b, calibrate the model.

Any of the following model parameters might vary from the initial values you were given.

K1, K2base, KVtardS, KRB, RCH1, and RCH2

Identify the simulated equivalents of the observations provided below in your MODLFOW output file. Calculate the residuals. Attempt to adjust the parameter values to minimize the residuals and consider the calibration criteria defined in the discussion.

The system and the initial values are as follows:
example flow system and initial values





After reaching your wit's end, go "BACK" and explore the automated calibration exercise.
