Seasonal Water Yield Model - Not Responding


I’m having trouble getting the model to run. It has run before (although not with successful outputs cause of errors) but when I try to run it again after fixing the errors it keeps lagging and “not responding”.

It just continues to hang before crashing at some point. I’ve uninstalled the software and reinstalled it but it just does the same thing.

Not sure if it’s my input, the software or my PC? I’ve attached a screenshot of the interface below.

Any suggestions or solutions?


Hi Karen,

It’s tough to say exactly what’s going on at the moment, but we’ve recently made some changes behind the scenes to the routing used in SWY that might also correct this issue. Could you try this development build and let us know if it’s still hanging or crashing for you?

Here’s the download link:


Hi James,

I’m pleased to report that is has worked and has produced an output!

Thank you so much!
