iMOD is freely available and open source software for a wide range of ground water modelling tasks. iMOD consists of user interfaces, pre- and postprocessing software and computational cores based on USGS MODFLOW source code to support analysis of groundwater flow.
Development of iMOD started in 2006. Since the end of 2021 two software products are distinguished: iMOD 5 and iMOD Suite.
The proven technology and expertise of iMOD is consolidated within iMOD 5. iMOD 5 supports structured calculations with MODFLOW2005 and structured MODFLOW 6 and can be coupled to the unsaturated zone model MetaSWAP. The model input and output can be visualised in its fast interactive viewer.
Important technological innovations will be developed in the new iMOD Suite, whereas iMOD 5 will be maintained the coming years, but will see no big new feature developments. Table 1 and Table 2 respectively provide comparisons between iMOD Suite and iMOD 5 for the components and supported MODFLOW6 packages.
