Title
SPDSS Task 50.1 - Review of Existing Approaches to Development of a Data Centered Approach for the SPDSS Groundwater Component - Pase 2
Description
This Technical Memorandum summarizes the existing data centered modeling process that has been implemented by the State for the Rio Grande Decision Support System (RGDSS) and identifies candidate graphical user interface (GUI) tools for screening and selection in subsequent tasks.

processing suite of programs. Program ModGUI allows selection and editing of control files, <br />launching of the pre- orpost-processor, and examination of log files. Each step in the process is <br />run individually, however program ModGUI facilitates this process. <br />2.4 Model Execution and Calibration Process <br />A complete set of MODFLOW input files is currently assembled from three sources: GMS, the <br />stream package processing suite of DMIs described in Section 2.3.4, and program StatePP. <br />These input files are then run in the State's version of MODFLOW. During the calibration <br />process, where parameters are changed, relevant programs may need to be re-run to generate new <br />MODFLOW input files. <br />2.5 Processing Output from the Groundwater Model <br />A series ofpost-processing programs are used to examine model results or prepare graphics. <br />Most of these packages are written in FORTRAN and have source code and documentation <br />available. Each of these packages are run individually using control files, either on a stand-alone <br />basis, or launched using program ModGUI. The major programs and their function are described <br />below. <br />^ GMS may be used to examine modeled heads and calibration statistics. <br />^ PM-Diamond operates directly on MODFLOW output files and is used to generate head and <br />flow contour maps, graphs of flow trends, head maps, and to generate report figures. This is a <br />commercial software package licensed by the State from Principia Mathematica that runs on <br />the Windows platform under a UNIX emulator. <br />^ ModDel calculates difference between individual simulations and operates directly on <br />MODFLOW output files. <br />^ ModEt partitions calculated evapotranspiration fluxes into native vegetation, subirrigated <br />meadow and subirrigated alfalfa components. <br />^ ModSum partitions calculated stream fluxes into individual streams and reaches. <br />^ ModBal summarizes water budget information for individual simulations by zones and layers, <br />breaking out the individual components. <br />^ ModParm summarizes aquifer parameters by zone for reporting. <br />^ ModCon summarizes a MODFLOW stream package output file for reports. <br />^ ModRepEt replaces the standard MODFLOW evapotranspiration package input file with one <br />that is independent of depth. <br />^ ArcView is used to visualize data and present some report figures. <br />
