The CLN Package in GMS
The Connected Linear Network (CLN) process was developed for MODFLOW-USG to model one dimensional connected features that are much smaller than a groundwater flow model's cells. The CLN Process can be used to replace multi-cell wells that would use the MNW1 or MNW2 package in other versions of MODFLOW.
Introduction
- GMS supports the CLN (Connected Linear Network) Package
- Display cells that have CLN package/GW process connections
- Display the CLN flow budget
The orange symbols in the screenshot show the CLN package/GW process connections
CLN Supports Multi Node Wells
- Like the MNW package, the CLN package supports multi node wells in MODFLOW-USG
- Simply create a CLN well using the conceptual model
CLN Wells in GMSGMS Map Shapefile to CLN
- Map a 2D shape file for surface stream network
- Map a 3D shapefile to the CLN package for something more complex
- Map values from the shapefile attribute table to the CLN package
- Generate the CLN grid geometry for the CLN package (displayed as a UGrid)
CLN Process Dialog
Data from the CLN package is displayed in the dialog
Values may be directly edited
Further development is based on user feedback/demand and can be sent to info@aquaveo.com
Items under consideration:
- Concentration observation
- Horizontal wells
- MODFLOW outputs displayed on the CLN grid (heads, CCF)
