Basic example of seawater intrusion with variable density MODFLOW6 - BUY and Model Muse - Tutorial

One of the greatest new features of the latest Model Muse version is the implementation of the BUY package for variable density and seawater intrusion modeling. The BUY package was already available in Modflow 6 but the resources to build a model was limited to scripts in Flopy or to build the packages for Modflow by hand, now with Model Muse much stress and pain could be relieved to simulate this type of groundwater model much relevant on the current climate change scenarios.

This tutorial shows the complete procedure to implement variable density / seawater intrusion modeling on a simple coastal aquifer with regional flow. The model runs over two steady / transient stress periods of 50 year each and has a cell with of 20 on the intrusion and 15 layers.
