    • ...Many studies have found that daily rainfall less than 10 mm does not have an important impact on runoff and erosion (Wischmeier and Smith 1978; Romero et al. 2007)...

    • ...The “Revised Universal Soil Loss Equation” (RUSLE; Wischmeier and Smith 1978; Renard et al. 1997) can provide a parametric evaluation system for the land degradation in terms of the soil erosion since it successfully integrates parameters of climate, soil, topography and vegetation and introduces a quantitative method for agricultural and bio-engineering conservation measures in order to sustain the natural resources...
    • ...Spatial prediction and uncertainty analysis of the RUSLE-K factor estimated by the soil erodibility nomograph (Wischmeier and Smith 1978) from a set of soil samples were carried out by (Wang et al. 2001) using a sequential Gaussian simulation...
    • ...In a semi-arid watershed, Bayramin et al. (2008) showed that soil properties and RUSLE-K, evaluated by the nomograph (Wischmeier and Smith 1978; Renard et al. 1997), statistically changed with land use changes...
    • ...The most widely used and frequently cited soilerodibility nomograph (Wischmeier et al. 1971; Wischmeier and Smith 1978) is the second equation to predict the RUSLE-K factor (Eq. 3). The soil erodibility nomograph comprises five soil and soil-profile parameters: percent of the modified Si (0.002‐0.1 mm), percent of the modified S (0.1‐2 mm), percent of the organic matter, and classes for soil structure and permeability...

    • ...Simple methods such as Universal Soil Loss Equation (USLE; Wischmeier and Smith 1978), Modified Universal Soil Loss Equation (MUSLE; Williams 1975) or Revised Universal Soil Loss Equation (RUSLE; Renard et al. 1991), are quite frequently used for estimation of gross...
    • ...The methods such as the USLE have been found to produce realistic estimates of surface erosion over small size areas (Wischmeier and Smith 1978; Ferro et al. 1998; Jain and Kothyari 2000; Kothyari et al. 2002 ;J ain and Goel2002 ;L ee2004; Onyando et al. 2005; Pandey et al. 2007)...

    • ...The values for the factors K, C and P are computed for different grids on overland and channel region as per Wischmeier and Smith (1978), Singh et al. (1981, 1992), Haan et al. (1994) using the information about landuse, soil texture and management practices adopted in the watershed...
    • ...K-values for mapped soil categories were then calculated for each of the mapping units using the Wischmeier and Smith (1978), Singh et al. (1981, 1992), Haan et al. (1994) procedure, and these are given in Table 1...
    • ...Generated landuse map of the watershed is given in Fig. 3. Based on the land cover categories, the attribute values for the C factor were assigned to individual cells from the tabulated values suggested by Wischmeier and Smith (1978), Singh et al. (1981, 1992), Haan et al. (1994)...
