Use of USLE

 There are three important applications of the universal soil loss equation. They are as follows:

 It predicts soil loss;

 It helps in the identification and selection of agricultural practices; and

 It provides recommendations on crop management practices to be used.

USLE is an erosion prediction model and its successful application depends on the ability to predict its various factors with a reasonable degree of accuracy. It is based on a considerably large experimental database relating to various factors of USLE.

Based on 21 observation points and 64 estimated erosion values of soil loss obtained by the use of USLE at locations spread over different regions of the country, soil erosion rates have been classified into 6 categories. Areas falling under different classes of erosion are shown in Table.

Modified Universal Soil Loss Equation (MUSLE)

The USLE was modified by Williams in 1975 to MUSLE by replacing the rainfall energy factor (R) with another factor called as ‘runoff factor’. The MUSLE is expressed as Y = 11.8 (Q x qp)^0.56 K(LS) CP where, Y = sediment yield from an individual storm (in metric tones), Q = storm runoff volume in m3, and qp = the peak rate of runoff in m3/s. All other factors K, (LS), C, and P have the same meaning as in USLE. The values of Q and qp can be obtained by appropriate runoff models. In this model, Q is considered to represent the detachment process and qp is the sediment transport. It is a sediment yield model and does not need a separate estimation of sediment delivery ratio and is applicable to individual storms. Also, it increases sediment yield prediction accuracy. From a modeling point of view, it has the advantage that daily, monthly, and annual sediment yields of a watershed can be modeled by combining appropriate hydrological models with MUSLE.

Topographic Factor (LS)

 LS is the slope length-gradient factor. The topographic factor is used to account for the length and steepness of the slope. The longer the slope, the greater is the volume of surface runoff, and the steeper the slope, the greater is its velocity. LS is 1.0 on a 9% slope and for a 22.1-meter long plot.
