Working with Your Data

Print this Topic Previous page Return to chapter overview Next page

The modeling workflows in Visual MODFLOW Flex are data driven. This means that you first need to load or create the appropriate data objects in order to use these at a particular step in the workflow. See the following table for some common examples:

 

 

If you have...

First you should...

Then you can...

River locations in a shapefile

Import these as Polyline data objects

Select this data object when creating a river boundary condition

Geological layers in a Surfer .GRD or ASCII GRD

Import these as Surface data objects

Select these data objects when defining horizons

Aerial photo with river locations

Import this as a Map image

Then Create a new Polyline data object

Digitize the polyline in a 2D Viewer

Select this new polyline data object when creating a river boundary condition

XYZ points for geological contacts

Import these as Points data objects

Then "Create Surfaces" from these data objects

Select these surfaces when defining horizons or numerical model layers

Raster Grid of Kx or Recharge data (from Surfer, ESRI .GRD)

Import these as surface data objects

Select these data objects when defining properties or Recharge boundary conditions

Visual MODFLOW (Classic) project or USGS MODFLOW files

Select the Numerical model workflow after creating a project

Select these files when prompted to Import Model. Learn more...
