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.[1] The CLN Process can be used to replace multi-cell wells that would use the MNW1 or MNW2 package in other versions of MODFLOW.

Conceptual Model

A CLN well can be added to a conceptual model by creating a point using the "Wells (CLN)" type. The geometry of the well screen can be set using the Use screen attribute for a single vertical screen. Otherwise, the generated well nodes include the grid layers specified for the coverage by its default layer range. For transient models, the CLN well node IBOUND values are disabled until the first stress period with a non-zero flow rate.

CLN Process Dialog

The CLN Process values can be edited in the CLN Process dialog. The dialog contains tables that can be accessed by selecting a table from the list at the left of the dialog. The Nodes table allows data for CLN nodes to be edited and viewed including the starting head and IBOUND values for each node. The connectivity of nodes can be edited in either the SegmentNodes table or the JAConnections table. Connections between the CLN process and the groundwater process can be edited in the GwConnections table. For transient models, changing IBOUND values can be edited in the TransientIBOUND table. A detailed description of CLN Process input is available with the MODFLOW-USG documentation available at the USGS MODFLOW-USG website.

CLN Wells Dialog

The MODFLOW CLN Wells Package is similar to the WEL Package dialog. It allows CLN well flow rates to be viewed and edited, and CLN wells can also be deleted. The Cell ID table column is the CLN Process node ID of the well.
