Hydrology and the universal soil loss equation by Richard H. Hawkins Download PDF EPUB FB2

Universal Soil Loss Equation (USLE) A = R x K x LS x C x P. A represents the potential long-term average annual soil loss in tonnes per hectare (tons per acre) per year. This is the amount, which is compared to the "tolerable soil loss" #: / Erosion and sediment yield in SWAT are estimated of each HRU with the Modified Universal Soil Loss Equation (MUSLE) developed by Wischmeier and Smith (; ).While the Universal Soil Loss Equation (USLE) uses rainfall as an indicator of erosive energy, MUSLE uses the amount of runoff to simulate erosion and sediment yield.

The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific.

Wischmeier and D. Smith, has been the most widely accepted and utilized soil loss equation for over 30 years. Designed as a method to predict average annual soil loss caused by sheet and rill erosion, the USLE is often criticized for its lack of applications.

where A is the soil loss per unit area, expressed in the units of K and period selected for R; R is the rainfall and runoff erosivity factor; K is the soil erodibility factor; L is the slope length factor; S is the slope steepness factor; C is the crop management factor; and P is the support practice factor.

The word ‘universal’ is used probably because the equation considers the five. A manual entitled Use of the Revised Universal Soil Loss Equation (RUSLE1) Mined Lands, Construction Sites, and Reclaimed Lands is available from the USDI-Office of Surface Mining, Reclamation, and Regulation that provides information concerning application of RUSLE to mining, construction, and reclamation sites.

Although the Revised Universal Soil Loss Equation (RUSLE) has been widely used for soil erosion estimation, the algorithm for calculating soil erodibility factor (K) in this equation remains limited, particularly in the context of China, which features highly diverse soil types.

In order to address the problem, a modified algorithm describing.
