  This study presents the differences and similarities between the MODFLOW-USG (Unstructured Grid version of MODFLOW) and traditional structured versions of MODFLOW 2005 in simulating a three-dimensional multilayer groundwater flow model in Quaternary aquifer east Nile delta in Egypt. A 390-borehole dataset was used to build a three-dimension stratigraphic model of the Quaternary aquifer. GIS-based conceptual model is mapping to represent the different boundary conditions such as lakes, river, drains, aquifer recharge, and discharge. The conceptual model is exported to the stratigraphic model; therefore, boundary conditions data are automatically arranged in arrays identical with the grid cells. MODFLOW 2005 and MODFLOW USG are combined with the computer-based program PEST to calibrate groundwater head distribution through the aquifer system. Groundwater levels measured in 1991 are used..
