Modeling impermeable walls with MODFLOW 6 and HFB Package - Tutorial

Modeling the performance and effectiveness of flow barriers or impermeable walls on the groundwater flow regime is a challenge due to the wall geometry / orientation and discretization requirements. The package Horizontal Flow Barrier was designed to simulate barriers of defined thickness and conductances that are located in between flow cells, in this way the flow barrier is independent for the model discretization. This package is not new, it dates back to 1993, and it was implemented on many MODFLOW versions.

We have developed a tutorial with an applied example of a flow barrier modeling in MODFLOW 6 and Model Muse. The tutorial discusses the impact of the barrier implementation, the new head distribution and the particle tracking simulation of flowpaths that surround the flow barrier.
