2 iMOD product lines
1. iMOD 5 (developments 2007-2021)
− Can be used for iMODFLOW and iMOD-WQ and limited functionality MODFLOW 6
− Development limited to bugfixes
2. iMOD Suite (2021 - ∞)
− Includes all new developments
− Supports structured and unstructured grids MODFLOW 6 and pre- and post
processing iMODFLOW and iMOD-WQ
− Now mainly (still) suitable for experienced modelers with experience in scripting.

Professionalization product development – Hydrology Team
• Increase cooperation between different software
• Adopt new way of working: Agile
iMOD Suite – iMOD Python
A collection of Python tools for groundwater modeling and MODFLOW input & output
• Preparing: e.g. rasterizing river shapefiles
• Formatting: produce MODFLOW input
• Extracting and post-processing: compare heads with piezometers, compute water balance
• Visualization: time series, map, cross-sections, 3D

iMOD Suite – iMOD Coupler
Is a shell for coupling hydrological kernels
• Separated source codes (no alterations within e.g. MF6)
• Robust, integrated testing
• Uses extension of basic modelling interface (XMI)
• Adding different drivers
− MODFLOW 6 – MetaSWAP
− MODFLOW 6 – MetaSWAP – D-Flow FM (Delft3D FM Suite 1D2D)
− MODFLOW 6 – RIBASIM

Python packages:
Xugrid
• Xarray extension to work with 2D unstructured
grids
Pandamesh
• Translates geospatial vector data (points,
lines, or polygons) to unstructured meshes
QGIS Tim
• A QGIS plugin for analytic elements: TimML
and Ttim
12
iMOD Suite new developments – iMOD Python
Highlights new functionality until December 2023
• MODFLOW 6 package checks
• Regridding, clipping, and masking of MODFLOW 6 models
• With simulation.open_head you can open heads from a simulation
• Define wells using x,y,z and HFB’s based on geopandas lines
Coming soon: partitioning for MODFLOW 6 parallel models
