Hello @ly11 -

I used a translator app to read the subject line, which I’ll write here for future reference (and hopefully is accurate enough): “Some results of water production are 0. How to solve this problem? The z parameter is already very low.”

If you search this forum for a phrase like “water yield 0”, you will find several posts that might help. Please review these, and they do not solve your problem, let us know what you tried.

Thank you very much for your reply, I have figured out what my problem was. I found out later that my own evapotranspiration was greater than the rainfall, so the water production result was 0.0.

Great, glad to hear that you solved the problem, thank you for letting us know.
