AHGW:Create MODFLOW Well Records

Create MODFLOW Well Records dialog

The Create MODFLOW Well Records tool is accessed by double-clicking on " Create MODFLOW Well Records" under the " Well Permitting" toolset under the " MODFLOW Analyst" toolset under the " Arc Hydro Groundwater Tools" toolbox. This tool takes point features with screen top and bottom elevations and a discharge rate and creates MODFLOW well records for the appropriate cells of a MODFLOW model. The new records are stored in the target WEL table and can be used to populate a MODFLOW well package file.
