How to adjust the z parameters

[lll_kkll]

Hello everyone, I would like to ask scholars a question about the water production module:
When I run the module, no matter how to adjust the z parameters, the result will not change, I want to ask what is the reason.
I would appreciate it if you could answer my questions.

Hi @lll_kkll,

Thanks for posting and welcome to the forums. If you search this forum for “z parameter” you will find many posts with the same question you have here. Could you explore those and see if they answer you question? Here’s one that could be what you’re experiencing.

Water yield Z parameter

Hi @dgw_awf, welcome back to the forums! The clearest possibility for this is if the climate equation from the User’s Guide. It looks like the \omega(x) parameter is calculated by a linear function that includes Z, but then the User’s Guide also says this: Z is an empirical constant, sometimes referred to as “seasonality factor”, which captures the local precipitation pattern and additional hydrogeological characteristics. It is positively correlated with N, the number of rain events per yea…
