Spatial Pattern A R Factor B K Factor C Ls Factor D P Factor In Here we combine slope (s factor), erodibility (e factor), rainfall rainy day ratio (r factor), and vegetation and soil indices (c factor) to locate erosion risk and prioritize. The word ‘universal’ is used probably because the equation considers the five principle factors which influence soil loss: k, r, ls, c, and p. in the 1980s, the usle was revised to incorporate additional research and technology developed.
Spatial Pattern A R Factor B K Factor C Ls Factor D P Factor In The ls factor can change with terracing. the c factor can change if different crops are used, or additional residue is left on the field at the time of planting because of reduced tillage intensity or if no till is used. The p factor can change by adopting contour tillage, contour strip cropping, or installing terraces. explore different management scenarios and calculate the predicted water erosion rate under those scenarios. Different input raster maps of ls factor, r factor, c factor, k factor and p factor were prepared using arc gis and raster calculation was made to predict the soil erosion over the catchment.

The usle is an empirically based equation, derived from a large mass of field data, especially erosion plots and rainfall simulator experiments, and computes sheet and rill erosion as follows: a=rklscp where a is computed soil loss, r is the rainfall runoff erosivity factor, k is a soil erodibility factor, l is the slope length factor, s is the. Similar to the sensitivity analysis of the r factor equa tions, testing different k factor equations to see the variation in erodibility values and then comparing these k factors with published values from similar soils would be a good way to test applicability. The rainfall erosivity factor, r, is a measure of the ability of rainfall to cause erosion. it is the product of two components: total energy (e) and maximum 30 minute intensity for each storm (i30). The rusle model is developed based upon five factors—(1) rainfall erosivity factor (r), (2) soil erodibility factor (k), (3) slope length and steepness factor (ls), (4) cover management factor (c) and (5) conservation practice factor (p) for the estimation of the average annual soil loss (a).
