SWY model running error InVEST 3.7.0

Hello,

I’m receiving this error from a Seasonal Water Yield run, someone can help me understand what it is about? I’ve been not able to solve it yet.

Thank you in advance for the help!

Hi Diego -

I have no idea what that error means either, but if you send me your data I’ll see if I can figure it out.

Hi Stacie

Thank you very much for your help!

Here is the Input data for the model. Please let me know if you can open it, otherwise, I can send you an e-mail.

Hi Diego -

Thanks for sending the input data. I’ve been playing with it, and still don’t know what specifically is breaking, so asked our software team to look at it.

For anyone wanting to do your own InVEST debugging, I started by looking at the output files, and found that quickflow (QF) seemed to calculate fine, but the output rasters for AET, and L_sum_avail (really all of the L rasters) have values of +/- infinity. Some of these are going into the Vri calculation (where the error occurred), so we need to trace back through the equations (see the User Guide for those.) L_sum_avail is where flow routing occurs, so perhaps it’s a problem with the DEM. I tried doing a QGIS Wang and Liu Fill on the DEM, but that didn’t help. And that’s where I’m punting to the software team…

Hi Stacie,

It is weird, I tried also to track the error and the problem occurs during the Vri Calculation, but I don’t understand where exactly occurs in the equation. I did an Annual Water Yield model too, and it worked fine for the same data.

Thank you very much for your help, let me know if the team solve the problem.

Hi Stacie,

There has been any answer from the software team?

Thank you in advance,

Diego.
