Getting Out of Squaresville: ArcGIS Tools for MODFLOW-USG
Track: Water Resources
Authors: Steven Silver
ArcGIS has proven an invaluable tool for generating and examining three-dimensional numerical models of groundwater flow based on the USGS MODFLOW code. A new version of MODFLOW has been released by the USGS (MODFLOW-USG) that includes unstructured and non-rectilinear grid capabilities that allow for more flexibility in representing aquifer systems. An ArcGIS based python toolset was developed to incorporate hydrogeologic information into this new gridding scheme. Examples will be presented.
