R Factor A K Factor B Ls Factor C And C Factor D By Different The word โuniversalโ 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. In this study, revised universal soil loss equation (rusle) model and geographic information system (gis) platforms were successfully applied to quantify the annual soil loss for the protection of.
A R Factor B Ls Factor C K Factor D C Factor E P Factor 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. Click on the links above to read the detail description of each factor. 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. Collecting five soil erosion factors; r factor from rainfall data, k factor from digital soil map of the world (dsmw) data, c factor from landsat 8 satellite image, and p factor from dem and references data.

Rusle2 is a powerful tool for conservation planning, inventorying erosion rates over large areas, and estimating sediment production that might become sediment yield in watersheds. 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 1992 nri provided r, k, ls, c, and p factor values for cropland. the cropland r, k, and ls values were applied to pastureland and forestland. the c factor was set at 0.04 for pastureland and 0.003 for forestland, and the p factor was set at 1 for both pastureland and forestland. The factors that contribute to the rusle model are the rainfall runoff erosivity factor (r), the soil erodibility factor (k), slope length and steepness factor (ls), cover management factor (c), and the support practice factor (p).
