What is C factor in Rusle?
C is the cover-management factor. The C-factor indicates how the conservation plan will affect the average annual soil loss and how that soil-loss potential will be distributed in time during construction activities, crop rotations or other management schemes.
How do you calculate Rusle?
RUSLE maintains the same empirically based equation as USLE to compute 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 slope steepness factor, C is a cover management factor, and …
What are the 6 Rusle factors?
R = rainfall-runoff erosivity factor.
What does C factor stand for and explain the term?
Abstract. The Revised Universal Soil Loss Equation (RUSLE)’s cover and management factor (C-factor) is one of the most difficult factors to obtain, mainly because long-term monitoring soil erosion plots under natural rainfall are needed.
What is support practice factor?
P is the support practice factor. The RUSLE P-factor reflects the impact of support practices an the average annual erosion rate. It is the ratio of soil loss with contouring and/or stripcropping to that with straight row farming up-and-down slope.
What is the difference between Usle and Rusle?
The Revised Universal Soil Loss Equation (RUSLE) is an upgrade of USLE that is land use independent. The major changes compared to USLE are in the values given for erosion as modified by vegetative cover and better calculations of the slope (LS) factors, as well as more advanced computerization.
What is Erosivity index?
Rainfall erosivity index is an important index to evaluate the soil loss due to rainfall. The quality and representativeness of erosivity index has significance in estimation of soil loss, as rainstorm is initiating factor in soil erosion by raindrops.
What is C factor in short circuit calculation?
C factor: This is the voltage correction factor (commonly referred to as C Factor). The C Factor is used for modifying equipment impedances and the driving point voltage. IEC recommends calculations for minimum and maximum short circuit currents.
What is C value for pipe?
For PVC pipe, the standard C value is 150. New steel pipe uses a C value of 140, but with use and corrosion a lower value is typically used.
What is the difference between Usle and RUSLE?
What is rainfall erosivity factor?
Rainfall erosivity is the kinetic energy of raindrop’s impact and the rate of associated runoff. The R-factor is a multi-annual average index that measures rainfall’s kinetic energy and intensity to describe the effect of rainfall on sheet and rill erosion.
What are the six factors of the RUSLE?
The RUSLE is composed of six factors: rainfall erosivity – R, soil erodibility – K, slope length – L, slope steepness – S, cover and management – C, and conservation practices – P.
Which is not a soil property but a RUSLE factor?
It is not a soil property but is defined by RUSLE definitions. The definition for K, and for all RUSLE factors as well, must be carefully observed to achieve accurate results. For example, using K to account for reduced soil loss from incorporation of manure is not proper and produces incorrect results.
How does rusle2 calculate net detachment each day?
A bucket can’t carry more than its capacity. RUSLE2 computes net detachment each day using a variation of the familiar USLE factors: where: a = net detachment (mass/unit area), r = erosivity factor, k = soil erodibility factor, l = slope length factor, S = slope steepness factor, c = cover-management factor, and p = supporting practices factor.
Is the annual erosivity R factor used in rusle2?
Although RUSLE2 can compute values for the familiar annual K, L, C, and P factors, those factors are not used in RUSLE2 and are not typically displayed in the RUSLE2 output. r factor: Annual erosivity R is the sum of the daily r values.
