Quoted from: https://water.usgs.gov/water-resources/legacy-software/ 

A version of MODFLOW, called MODFLOW-LGR (for Local Grid Refinement) was developed (Mehl and Hill, 2005) to support the use of locally refined grids to simulate groundwater flow. MODFLOW-LGR allows smaller parts of a larger model domain to be refined without refining the entire model. Mehl and Hill (2007) expanded the original scope of MODFLOW-LGR to include multiple areas of refinement within a single model domain. Mehl and Hill (2010) allows rivers simulated with the Streamflow-Routing Process (SFR) to be routed through locally refined grids. The current version (2013) couples grids using the ghost-node method rather than the shared node method (Mehl and Hill, 2013). MODFLOW-LGR is integrated in the new MODFLOW-OWHM version of MODFLOW. Local grid refinement functionality is also available through MODFLOW-USG.
