3. Development
• The pre-assessor was developed by André Blonk from Tauw, and
used in various Tauw projects
• The iMOD-version was developed by André Blonk and Peter
Vermeulen
• To be released in new iMOD version
4. Advantages
• Water balances per budget term, time step and layer
• Water balances for multiple zones with option to save
fluxes between zones
• Extensive options for data aggregation and
visualization
• Generating illustrative plots with (average) fluxes in
zones
5. Usage
• Generating water balance can be done in iMOD GUI
and iMOD batch (calculations can be time consuming)
• Visualization of water balances in iMOD GUI
• Postprocessing water balance data can be done in
Excel, R, Python, etc…
14. Summarizing
• Powerful tool to better understand the groundwater
system and/or model
• All generated data summarized in csv-file, which can
be post-processed
• Various aggregation options to better interpret
generated data
• Various visualization options to fit usage and user
preferences
