GW_Chart: A Program for Creating Specialized Graphs Used in Groundwater Studies

Release Date: June 26, 2020

Overview of GW_Chart

GW_Chart is a program for creating specialized graphs used in groundwater studies. It incorporates the functionality of two previous programs, Budgeteer and Hydrograph Extractor and adds additional new features. There are seven major types of graphs created with GW_Chart:

Calibration Plots
Water Budget Plots
Hydrographs
Lake Plots
Piper Diagrams
Cell Water Budgets
Farm Budgets

It reads data from the following programs to create these plots:

ZONEBUDGET
MODFLOW
MOC3D
MODFLOW2000-GWT
SUTRA
MT3D
HST3D
UCODE-2005
OPR-PPR

GW_Chart can also convert cell-by-cell budget files or zeta file generated by MODFLOW to text files.
