Abstract (EN): Interface roughness in limited local sandpile (LLS) displaying self-organized criticality (SOC) and their noncritical varients in one dimensions were analyzed. It was suggested that the value of surface roughness depends on whether it is measured about the nontrivial steady state profile or about the mean instantaneous surface. It was found that two seemingly equivalent definitions of surface roughness in SOC system yield different asymptotic scaling exponents. It was also suggested that this ambiguity is due to the special scaling properties of the nonlinear steady state surface.
