In this video, I show the calculation of LS factor ( L= slope lenght,S= Slope).
LS factor is used in USLE/RUSLE EQUATIONS for soil erosion Modeling.
In this case i used the equation as writen below (Hilborn,2012):


Ls=(("fac"*30/22.1)^0.5)*(0.065+0.045*"slopprcent"+0.0065*("slopprcent"* "slopprcent"))


Fac is the Flow accumulation and Slope in %
In this case used DEM 30 m ( Fac*30)
