MODFLOW-USG (UnStructured Grid version of MODFLOW) provides a significant advancement in groundwater modeling. Along with a new set of capabilities, there are several changes to the underlying MODFLOW concepts. Thus there is a need to better understand the differences and similarities between the UnStructured version of MODFLOW and traditional Structured versions of MODFLOW (including MODFLOW-2000, -2005, -NWT, -LGR). This page contains links to several resources, white papers, and multi-media demonstrations of the capabilities of MODFLOW-USG and Visual MODFLOW Flex.
