MODFLOW DATA MODEL An extension of the Arc

MODFLOW DATA MODEL An extension of the Arc Hydro Groundwater Simulation feature dataset

MODFLOW Data Model n n n Data standard for storing MODFLOW models in a GIS database Importing models built externally Archiving calibrated models Building new MODFLOW models inside Arc. GIS Custom scripts for analyzing/modifying models can be developed as geoprocessing tools
