Following a brief introduction to groundwater modelling, this webinar introduces the capabilities of the U.S. Geological Survey (USGS) MODFLOW software. International groundwater modelling experts demonstrate a number of practical examples and explain methods for model development with the use of MODFLOW-2005 or MODFLOW-OWHM together with public domain tools. Finally we provide a practical update on a newly developed MODFLOW-6 suite.
The key issues to be addressed will be:
- What is a groundwater model?
- What does MODFLOW do?
- Brief comparison of open source MODFLOW modelling platforms and GUIs
- Practical examples demonstrating capabilities of MODFLOW and its modules.

At least a basic knowledge of groundwater is recommended.
No previous modelling experience is required.
