What is C factor in RUSLE?
C Factor. C is the cover-management factor. The C-factor is used to reflect the effect of cropping and management practices on erosion rates. It is the factor used most often to compare the relative impacts of management options on conservation plans.
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?
There are six factors parameter maps were considered in RUSLE; rainfall erosivity factor (R), soil erodibility (K), slope length and steepness (LS), cover management(C) and conservation practice (P).
What is RUSLE method?
The Revised Universal Soil Loss Equation (RUSLE) is an empirical erosion model recognised as a standard method to calculate the average risk of erosion on arable land. The method is efficient in terms of costs for data provision, model parameterisation and modelling.
How do you calculate C Factor?
To calculate the C Factor, measure the flow, pipe diameter, distance between two pressure gauges, and the friction or energy loss of the water between the gauges.
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 the difference between erosivity and erodibility?
Conceptually, rainfall erosivity is the capacity of rain to produce erosion, whereas soil erodibility is the susceptibility of the soil to be eroded.
What is the difference between Usle and RUSLE?
Who developed RUSLE?
Both RUSLE1. 06c and RUSLE2 were developed and are maintained principally by the USDA-Agricultural Research Service (ARS), the USDA-Natural Resources Conservation Service (NRCS), and the University of Tennessee. RUSLE began development at the National Soil Erosion Research Laboratory in the early 1990’s.
What is RUSLE used for?
RUSLE is the method, most widely used around the world to predict long-term rates of inter-rill and rill erosion from field or farm size units subject to different management practices.
