An unstructured grid version of MODFLOW called MODFLOW-USG has recently been released to provide flexibility in gridding for MODFLOW solutions. Additional tools surrounding this code that have been developed and are under further development include various grid generation schemes, graphical user interfaces (GUIs), particle tracking routines, zone budget routines, parameter estimation routines, and dual domain flow and transport simulation capabilities among others. This presentation summarizes the current version of MODFLOW-USG —how it works, when and where it should be used, and current and future development plans.
