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

GMS Map Shapefile to CLN

  • GMS supports the CLN (Connected Linear Network) Package
  • Display cells that have CLN package/GW process connections
  • Display the CLN flow budget

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)
