Calibrating River Conductance in MF6 with PyEMU

[Omowumieru]

Hi,

I set up my FloPy mf6 model to calculate river conductance using the formula (Conductance = Riverbed K * Length * Width / Thickness), so each cell has a different conductance based on its segment length. I only have information about riverbed K values and don't know the exact conductance values or range.

Should I set calibration bounds (ult_ubound, ult_lbound) on riverbed K and let PyEMU adjust conductance implicitly based on my FloPy setup (if possible)? Or do I need to set bounds directly on conductance, even though I don't know these values?

I'm not sure which approach is best. Any guidance would be appreciated!

Thanks!
