request for assistance

I am estimating soil loss using the RUSLE model. However, when I calculated the LS factor, most of the pixels resulted in no value. Please tell me how to correct the problem. I used the formula: LS = Power("wateshed_acc" * 30 / 22.1,0.4) * Power(Sin("slope_deg") * 0.01745 / 0.0896,1.3)

Hi @abebebezu,

You will have more success getting help from these forums if you post some additional information:

Which ArcGIS product are you using? Which version?
Which spatial analysis tool are you using?
What kind of data are your performing the analysis on?

Then perhaps post your question in the appropriate product forum.

Hope this helps,

Hi @abebebezu,

I've moved this thread to the appropriate discussion forum, as I am unable to answer your question.

FYI, ArcMap 10.4.1 was retired on Feb 1, 2022.

You may want to consider migrating to ArcGIS Pro.

Hope this helps,
