Hello everyone,

I am using the ndr model but in the results there are areas without information and I would like to know why?

Thank you!

Hi @mfcnico -

If you look at the stream.tif output from the model, you’ll probably find that the NoDatas correspond with the stream network. NDR does this because it does not do any sort of in-stream calculations, so the assumption is that once nutrient hits a stream, the calculations stop and it becomes export.

If the NoDatas do _not_ correspond with the stream network, then take a look at your inputs and make sure that none of them are missing data in those places, since anywhere one spatial layer has NoData, the output will have NoData.
