Hello @MarysiaDB, welcome to the forums!

I moved your post over here to a new thread since the other one ([link here](https://community.naturalcapitalalliance.org/t/invest-sdr-sediment-export-overestimation/1997)) hadn’t had any activity in about 3 months, even though it was a similar subject.

Could you take a look at the LS factor? How does it compare to the LS factor calculated by another tool, such as the SAGA module in QGIS? We have noticed some discrepancies in the LS factor on some landscapes, so I’m wondering if that explains what is happening here.

Thanks,  
James
