SDR Model

Hi all,

I'm using the SDR model to make predictions about the sediment delivery of a watershed. I added all the input data and run the model in InVEST 3.3.2 (Windows). I encouter an error that keeps returning and I believe my input data are correct. I also tried running it on another PC and I tried version 3.3.3 (32 bit), but that didn't work.

I get the following error: Error: valueError encountered
In the attachments is my log file.

Does anybody know what might be the issue here?

Thank you in advance,

Kind regards,

    Hi @msuresh -

    That error usually indicates that you have an LULC raster class with a value of 8 that does not have a matching lucode entry in the biophysical table (for usle_c and/or usle_p.) But you've checked your biophysical table and you have the correct entries?
