Trend Analysis of LS Factor at Various Slope Length using Nomograph

Abstract

LS factor is one of the five important factors of the USLE/RUSLE equation. Most researchers are using Universal Soil Loss Equation (USLE) and Revised Universal Soil Loss Equation (RUSLE) methods to calculate the estimation of soil erosion. It is very difficult for the researchers to calculate the LS factor, due to its complexity. This paper introduces innovative polynomial trend analysis for various fixed slope lengths. These trends are easy to calculate with the same accuracy as given by RUSLE and USLE, with an easy approach. The paper starts dealing with the LS factor introduced by RUSLE/USLE and draws the nomograph based on derived results. These results are also used in the creation of the trend polynomial curve.
