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,

Thank you for the immediate response 

• I am using ArcMap version10.4.1
• The spatial analysis tool used was raster calculator from map algebra
• The calculation was on raster data

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,
