General Module Function
The subset_layers module allows you to subset the output of Krig_3D_Geology so that downstream modules (Krig_3D, 3D_Geology_Map, Geologic Surface) act on only a portion of the layers kriged.
subset_layers is used to select a subset of the layers (and corresponding surfaces) export from Krig_3D_Geology. This is useful if you want (need) to krige parameter data in each geologic layer separately.
This is not normally needed with contaminant data, but when you are kriging data such as porosity that is inherently discontinuous across layer boundaries, it is essential that each layer be kriged with data collected ONLY within that layer.
Subset_layers eliminates the need for multiple Krig_3D_Geology modules reading data files that are subsets of a master geology. Inserting subset_layers between Krig_3D_Geology and Krig_3D allows you to select one or more layers from the geology.
This functionality is very useful when you want to krige groundwater and soil data using a single master geology file that represents both the saturated and unsaturated zones.
Module Input Ports
subset_layers has one input port which only accepts input from Krig_3D_Geology or Read_EVS_Geology.
Module Output Ports
subset_layers has one output port that outputs a subset of the layers created by Krig_3D_Geology. It connects to modules such as Krig_3D, 3D_Geology_Map, or Geologic Surface.
Module Control Panel
The control panel for subset_layers is shown in the figure above. There are only two parameters. These are the "first layer" and "last layer" to be included in the subset. If inappropriate values are entered by the user, the module will revise the values to the nearest valid values.
