Water yield output 0

I’m having a bit of a problem with my annual water output output. The water part is 0. I wonder if this is reasonable. If it is wrong, what is the cause of the error and how to fix it.

Hi @qiaoxiao1997 -

Please provide more information about your issue. When you say “the water part is 0”, what are you referring to? The wyield.tif output? One of the aggregated results in watershed_results_wyield.shp? Something else? Can you provide an image of the result that is 0? Did you get any errors when running the model?

The wyield.tif output。red is for water

Thanks for the additional information @qiaoxiao1997. Since the 0 values correspond to water, what are the kc and root_depth values for that class in your biophysical table? Looking at the model equations, does that explain the 0 values?
