Hello,

I'm a beginner user of the model. I'm trying to create the HRUs and it all seems to be going really well, I get the full HRU count at 296, there's no error message when I click the create HRUs icon... BUT, when the operation finishes this message pops up: "HRUs done: 0 HRUs formed in 0 subbasins". I've tried every single method in the Single/Multiple HRUs section and it doesn't change the outcome. And the weirdest thing is that it enables the step 3 icon "Edit Inputs and Run SWAT". I have no ideia what's going on. Can anyone shed light on this?

Hi Lara,

Please check the projection for all your datasets, Reprojection might solve the problem.

Hi,

I've received other answers by e-mail and, after analyzing the suggestions, it turned out that the problem was indeed the projection. I prepared my data in R and the function I used changed solely the crs, so I had an crs in meters unit but the resolution remained in degrees. After this was realized, I found another function that suited the purpose and the model ran just fine.
