Nodata values in valleys

Hello, when I was using the SDR module of the Integrated Valuation of Ecosystem Services and Trade off (InVEST) software, the output results of the rkls. tif and usle. tif files showed many Nodata values in the valley position when loaded into ArcMAP. What is the reason for this? Thank you.

Hello @coco and welcome to the forum! I moved your question here to a different thread because it appears to be distinct from the other, years-old thread that this post was originally made on.

Would you please compare the streams.tif output to the regions that you see in the valleys that have nodata values? If the streams.tif layer doesn’t explain all of the nodata values, please attach the full logfile from your most recent run of the model so we can start to take a closer look.
