Two auxiliary programs

  • Modelviewer

    • 3D visualization of input or output

  • GW-Chart

    • plots information about model fit etc.


ModelViewer– a program for displaying results of ground-water modelsby Paul Hsieh & Richard Winston, USGS


ModelViewer

  • Free USGS program. Obtain from:http://water.usgs.gov/software/ground_water.html

  • Supports 3D visualization of input or output for a suite of models, including MODFLOW-2005, MODFLOW-2000, MODFLOW-2000 with Ground-Water Transport Process, MODFLOW-96, MOC3D, MODPATH, MT3DMS, SUTRA, and PHAST


ModelViewer

  • Reads in the MODFLOW-2005 ‘name’ file then imports existing model input and output files

  • Must have run the model and have head output.

  • You have an executable or a shortcut to ModelViewer in your bin-plotting folder

  • Open model created in exercise 3.1.


ModelViewer Instructions

  • The next slide provides instructions for using ModelViewer to visualize heads and hydraulic conductivity (K)

  • The following slide provides instructions for using ModelViewer to visualize an objective-function. Only available when using UCODE_2005.

  • For more information, see the ModelViewer online help system.


ModelViewer Instructions: head and K

  • Execute ModelViewer. Start with visualizing hydraulic heads.

  • Under the File menu item, select New.

  • Model Selection dialog box: select Modflow 2000.

  • Modflow 2000Data Files dialog box: browse to name file (e.g. ex3.2.nam).

  • Data Selection dialog box: keep defaults. The model domain appears.

  • Show menu item: select Solid, then Model Features.

  • Model Features dialog box: select both model features.

  • Toolbox menu item: select Geometry and set z to 10 to specify 10x vertical exaggeration. See a floodmap of hydraulic heads.

  • Show menu item: select Colorbar

  • Rotate by clicking and dragging any corner. To return to original, under the Action menu item click View From Direction and choose +z.

  • Now, visualize hydraulic conductivity (K).

  • Toolbox menu item: select Data and choose K along rows.

  • Toolbox menu item: select Solid; select Blocky.

  • Toolbox menu item: select Crop. Reduce the Max for Z until you can see first the hydraulic conductivity of the confining unit, and then of the lower model layer.


ModelViewer Instructions: SOS

  • Only available with UCODE_2005.

  • Execute ModelViewer.

  • Under the File menu item, select New.

  • Model Selection dialog box: select UCODE 2005 - SOS.

  • UCODEData File dialog box: browse to the ex5.1 directory. Click on the _sos file.

  • Data Selection dialog box: keep defaults. See the parameter domain.

  • Show menu item: select Solid.

  • See the previous slide for ideas for manipulating the graph.


Two auxiliary programs

  • Modelviewer

    • 3D visualization of input or output

  • GW-Chart

    • plots information about model fit etc.


GW_Chartby Richard Winston, USGS


GW_Chart

  • Free USGS program. Obtain from:

    http://water.usgs.gov/software/ground_water.html

  • Plots results from many of the files for which the filename extension starts with “._” (e.g. ex5.2._b) These are produced by MODFLOW-2000, UCODE_2005, and some other programs. UCODE_2005 calls these “data-exchange” files

  • GW_Chart is very useful for quick analysis of model fit, sensitivities, parameter value changes by regression, etc.


GW_Chart

  • The user identifies the program that produced the files (MODFLOW-2000 or UCODE_2005) and then navigates to one of the files. GW_Chart assumes the rest are in the same directory and have the same filename prefix.

  • Must have run the model and have the data-exchange files.

  • You have an executable or a shortcut to GW_Chart in your bin-plotting folder

  • Use GW_Chart to produce the following graphs

    • Composite and dimensionless scaled sensitivities for the exercises in Chapters 4 and 7

    • Updated parameter values for exercises in Chapter 5, the residual analysis for the exercises in Chapter 6, and the parameters and their confidence intervals in Chapter 7.


Instructions for GW_Chart

  • Execute GW_Chart. The window on the next slide appears.

  • Identify the program that produced the files to be plotted in a drop-down menu on the top right (MODFLOW-2000 or UCODE_2005)

  • Click File on the top left part of the window and then “Open File”. Navigate to the directory containing the files of interest. Open one file. GW_Chart looks for other files in that directory with the same filename prefix and filename extensions that it recognizes. These files are listed in the dropdown menu labeled “File:” in the upper middle part of the window.

  • The filename extensions and the associated file content are described in the documentation of MODFLOW-2000 (Hill and others, 2000, p. 28-29) and UCODE_2005 (Poeter and Hill, 2005, p. 231-233).

  • Graphs of other data sets are obtained by choosing other files from the drop-down menu labeled “Files:”


Initial GW_Chart window


GW_Chart: three issues

  • What to do if the expected files are not being produced.

    • MODFLOW-2000: check the file for all observations (Hill+, 2000, p. 27)

    • UCODE_2005 keyword DataExchange (Poeter and Hill, 2005, p. 58)

  • Graph options are provided by GW_Chart in a popup window.

  • Graph produced for the file with extension _ws

    • Vertical axis used for weighted residuals has a scale using multiples of the standard error of the regression. This has advantages discussed later in the course.
