Dynamic River Conductance

This example is based on the Advanced MODFLOW Training Class, November 22, 2024, Deltares, NL

There the problem is described as follows:

In this example, we are going to use the API to modify the river package so that the conductance is greater when the groundwater system is discharging to the river and smaller when the river is discharging to the aquifer. This example is inspired by Zaadnoordijk (2009), which used a combination of general head and drain boundaries to increase the conductance when the aquifer is discharging to the river.
