How to efficiently apply Geology from Shapefiles to MODFLOW with ModelMuse with Global Variables

On the MODFLOW groundwater model construction process in Model Muse there are tools to import hydrogeological parameters as hydraulic conductivity and boundary conditions from shapefiles assigning the parameter values from the spatial object metadata. This type of workflow is useful for idealized aquifers or simple hydrogeological assessments; however on groundwater models at regional scale the calibration process requires the quick and repetitive change of the hydrogeological parameters and boundary conditions to evaluate the hydraulic response against observed data.

For model calibration the use of Global Variables (Data/Edit Global Variables...) of Model Muse makes relatively easy, ordered and with better change control the calibration process. This tutorial gives the procedure to implement Global Variables for the hydraulic conductivities of 15 hydrogeological units distributed on a model of 560 square kilometers.
