Groundwater (MODFLOW)

Data sets related to groundwater modeling (MODFLOW) have been developed for the San Luis Valley as part of the Rio Grande Decision Support System and for the South Platte alluvial aquifer system as part of the South Platte Decision Support System. These datasets can be used as a baseline dataset or as a starting point for the development of other datasets.

Major Features:
  • Data sets provide an overall modeling framework for MODFLOW in the San Luis Valley and South Platte alluvial aquifer.
  • Includes reports documenting the development and calibration of the San Luis Valley and South Platte alluvial aquifer groundwater model and data sets
Common Uses:
  • Input baseline model data as a starting point for a groundwater model in the San Luis Valley and South Platte alluvial aquifer.

Modeling Data: The latest modeling datasets are available via the links below. For archived datasets or other information, search our Laserfiche system using the Decision Support System template.

  • The latest dataset for the Rio Grande Basin can be downloaded from DWR's RGDSS modeling site.
  • Due to its size, the South Platte Decision Support System model dataset can be requested from Brian Macpherson.   
    • There are 2 versions of the model dataset. One has model input files and the batch file required to run the model warmup period and then the 1950-2012 model. The other has all input datasets, the StateDGI Toolbox, model input files, batch file required to run the model warmup period and then the 1950-2012 model, and scenarios created by the contractor. The scenarios are described in the model documentation below.
