How do you calculate RUSLE?

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 is the K factor in RUSLE?

K factor is soil erodibility factor which represents both susceptibility of soil to erosion and the rate of runoff, as measured under the standard unit plot condition. Soils high in clay have low K values, about 0.05 to 0.15, because they resistant to detachment.

What does the P stand for in the Rusle equation?

P = support practice factor.

What is Rusle model?

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.

What is erodible soil?

Erodibility describes or is a measure of the inherent resistance of geologic materials (soils and rocks) to erosion. Highly erodible geologic materials are readily displaced and transported by water.

What makes a soil erodible?

Soils having a high silt content are the most erodible of all soils. They are easily detached and they tend to crust and produce large amounts and rates of runoff. Values of K for these soils tend to be greater than 0.4.

What is RUSLE model?

What is the difference between USLE and RUSLE?

The RUSLE uses the same formula as the USLE, but with improvements in the estimation of many Factors. RUSLE can take into account more complex combinations of tillage practices and cultivation practices as well as a wider variety of slope forms.

Who developed RUSLE model?

Wischmeier and Smith
RUSLE (Wischmeier and Smith, 1978) compute the average annual erosion expected on field slopes using in Eq. (1).

What is soil erosion mapping?

Soil Erosion Maps Rainfalls of eight rain gauge stations are taken to calculate the rainfall erosivity (R) and are interpolated by Inverse Distance Weighting (IDW) method to show spatial distribution. Data processing and analysis of USLE factors is performed in the form of raster layers.

Which soil texture is most erodible?

What is erodibility and Erosivity?

Abstract. Conceptually, rainfall erosivity is the capacity of rain to produce erosion, whereas soil erodibility is the susceptibility of the soil to be eroded.
