This can be obtained by the frequency analysis of soil loss measurements or by suitable soil erosion models. The USLE‐MM and USLE‐MB are two empirical USLE‐M (Universal Soil Loss Equation – Modified) type models which were developed using runoff and soil loss measurements collected at the Sparacia (South Italy) : Vincenzo Pampalone, Vito Ferro. How to Calculate Erodibility Factor (K) of Soil using Williams Equation and FAO Soil in ArcMap - Duration: Tech-tutor with Fitsum 2, views.
Soil erosion is a natural process causing grave land degradation problems. In Tunisia, soil erosion represents a serious environmental problem. Both man-made and natural phenomenon is reducing acres of agricultural land. The problem of soil erosion by water is very critical in Lebna watershed. In fact, Lebna is a town in the northeast of Tunisia and it seems high time to protect water Cited by: The same holds for estimating plant cover and soil management effects on soil loss. The final topic discussed is erosion by wind. The individual factors determining soil loss are presented on the basis of an empirical erosion equation, allowing the prediction of the potential average soil loss per year.
Using universal soil loss equation for soil erosion assesment in agricultural land water, both spatially and temporally. Among these methods, the modeling was used most often. Thus, a wide range of soil erosion models was developed and used worldwide: Universal Soil Loss Equation (USLE) (Wischmeier, W.H. and Smith, D.D., , ). sion. MUSLE does not include soil loss that can occur through ephemeral gully or gully erosion processes or erosion of furrows or basins during gravity irrigation events. MUSLE is a modification of the Universal Soil Loss Equation (USLE). USLE is an estimate of sheet and rill soil movement down a uniform slope using rain-.

In this study, the Universal Soil Loss Equation (USLE) was combined with GIS technologies to estimate the potential soil loss from areas within the Oued El Makhazine watershed, generatesoil erosion severity maps, and analyze areas of critical soil erosion conditions which claim urgent need for convenient conservation measures and land Size: 2MB.

3, D Bonn, Germany E-mail: [email protected] The most accurate soil loss equation that is now field operational is the universal soil loss equation developed by Smith and Wischmeier (, ). The equation is most comprehensive and includes six variables important in soil erosion by water.
While some soil loss is inevitable, and must be accepted, most soil erosion is rapid and damaging. Hazard is best assessed by the Universal Soil Loss Equation.
Conservation practices include crop management, mechanical protection, and control of gullying. Predicting Soil Erosion by Water: A Guide to Conservation Planning with the Revised Universal Soil Loss Equation (RUSLE) Author: US EPA, OW, OWM, Water Permits Division Subject: Contains information on the R factor.
Keywords: npdes, soil erosion, r factor, rusle. USLE was the first empirical erosion equation that was not tied to a specific region of the United States, thus the title "Universal" Soil Loss Equation. The USLE has been used in more than countries to guide conservation planning, assess soil erosion for conservation policy development, and estimate.
A calculation of soil losses using the USLE may also be done in OMAFRA's NMAN Nutrient Management Software, SOF The soil loss value generated from the USLE equation is used to determine the "soil erosion rating value" in the calculation of the Phosphorus #: / The following Soil Erosion Calculator is a Tool to calculate the average annual rate of erosion.
It is based on the USLE equation and can be applied globally. Nevertheless, the USLE equation and thus the Soil Erosion Calculator has two main limitations that need to be considered. Foreword. Soil erosion has been a serious problem for agriculture back through the centuries. When man started to cultivate the soil and plant and husband crops, soil erosion was accelerated.
Prevention or reduction of soil erosion keeps the most fertile layer, the top soil, in the field, avoiding losses of plant nutrient elements and organic matter. Soil Erosion Digital Elevation Model Sediment Yield Universal Soil Loss Equation Slope Length.

Estimating your soil erosion losses with the universal soil loss equation (USLE). Urbana, Ill.: University of Illinois at Urbana-Champaign, College of Agriculture, Cooperative Extension Service, From these, Universal Soil Loss Equation (USLE) represents the most practical method to estimate soil erosion potential.
Also, the equation is very easy to be implemented in the geographic. ESTIMATING SOIL EROSION FROM WATER USING THE REVISED UNIVERSAL SOIL LOSS EQUATION, VERSION 2.

Terrace spacing can also be based on the average annual soil erosion rate estimated using erosion prediction technology such as the Revised Universal Soil Loss Equation (RUSLE).
The terraces are spaced so that the estimated erosion rate on the inter-terrace interval is less than the soil loss tolerance value assigned to the site-specific soil. The following are examples showing how the Revised Universal Soil Loss Equation is used for estimating soil losses: Assume Cortland, New York, as the locale of a construction site.
The disturbed site is 50 acres in size, with an average gradient of 8% and an average slope length of feet. Revised Universal Soil Loss Equation.

Soil erosion caused by water has been assessed by some developed models, including the Water Erosion Prediction Project (WEPP), Universal Soil Loss Equation (USLE), the Revised Universal Soil Loss Equation (RUSLE), and the Erosion Productivity Impact Calculator (EPIC) (Laflen,Renard et al.,Williams et al.,Wischmeier and Cited by:.
The Universal Soil Loss Equation (USLE) enables planners to predict the average rate of soil erosion for each feasible alter- native combination of crop system and management practices in association with a specified soil type, rainfall pattern, and topography.
