46 Processing Modflow Fig. 2.37 The List of Calibration Parameters (PEST) dialog box Check calibration results Fig. 2.38 The Run PEST dialog box During the automatic calibration several result files are created. PEST writes the optimized parameter values to the input files of MODFLOW (BCF.DAT, WEL.DAT, etc.) and creates a detailed run record file path\PESTCTL.REC, where path is the folder in which your model data are saved. The simulation results of MODFLOW are updated by using the optimized parameter values, which are saved in a separate file PESTCTL.PAR. 2.3.1 Perform Automatic Calibration with PEST
Processing Modflow 47 Note that PMWIN does not retrieve the optimized parameter values into the data matrices. Your (PMWIN-) model data will not be modified in any way. This provides more security for the model data, because an automatic calibration process does not necessarily lead to a success. If you want to operate on a calibrated model, you can import the model by choosing Convert Model... from the File menu, see Chapter 3 for details. You can create a scatter diagram to present the calibration result. The observed head values are plotted on one axis against the corresponding calculated values on the other. If there is exact agreement between measurement and simulation, all points lie on a 45° line. The narrower the area of scatter around this line, the better is the match. < To create a scatter diagram for head values 1. Choose Graph < Head-Time from the Tools menu. A Head-Time Curves dialog box appears. 2. Click the button Scatter Diagram » PMWIN shows the scatter diagram (Fig. 2.39). See Chapter 5 for details about the use of this dialog box.
