Problems with setting the range of values for the “Rch_A” in FlexFlux model parameter

[Xiangbo000]

When I was studying the pastas tutorial, I had some questions about the reasonableness of the optimization results of the final parameters. For example, in the study of Non-linear recharge models, the final optimization result for “rch_A” is 0.44, and I would like to ask if this means that a recharge of 1mm will ultimately create a water level rise of 0.44m?

Hi @Xiangbo000. Yes this is the correct interpretation. Also see the Pastas paper on this:https://ngwa.onlinelibrary.wiley.com/doi/full/10.1111/gwat.12925
