Hi, i'm using the follow equation to create an LS factor for RUSLE, if anyone has used a similar equation did they divide the output by 10 or 100?
LS = Power(FlowAccumulation * 50 / 22.1, 0.4) * Power(Sin(Slope * 0.01745) / 0.09, 1.4) * 1.4
It has been used in studies [1,2] and my results seem more accurate when dividing by 10.
Thanks.
