About 42.1% (5317.23 ha) of the catchment area was predicted to have moderate risk of erosion, with soil loss between 5 - 25 ton·ha-1·year-1 Soil loss triggered by water erosion constitutes a major issue that causes several environmental and socioeconomic concerns. Pierre Y. The present study, for the first time, attempts to estimate the soil loss of Nepal through the …. The objectives of this study were to estimate Hirna river watershed. The result showed that the average soil loss in the surveyed fields was 36t/ha provided that the contribution of inter-rill erosion assumed to be 25% of the actual soil loss (taken from different literatures). It has also deteriorated the water quality and caused negative effects on the aquatic ecosystem. comparison to soil water loss (m3/m3) measured throughout the growing season. While it can estimate long - term annual soil loss and guide conservationists on proper cropping, management, and conservation practices, it can not be applied to a specific year or a specific storm change in the soil per unit of applied external force or energy. Also the USLE is restricted to rill and. This study aims at estimating and quantifying the amount of soil loss as well as highlighting potential areas to erosion risk, using the Revised Universal Soil Loss Equation (RUSLE) combined with GIS and remote sensing Land degradation in the form of soil erosion is worldwide phenomenon leading to nutrient loss and is a major constraint to farming activities and sustainable agricultural development. The difference between the three K factor scenarios is almost 4%, which is pretty low thus, no influence on the soil erosion results. The study was conducted on a highly precipitated, rugged, tropical forested with steep slope watershed during 1992 to 2009 The USLE soil loss equation is: A = R K L S C P (8.1) where A is the computed soil loss per unit area, expressed in the units selected for K and for the period selected for R (in common practice these are usually selected such that they compute A, …. The underestimation of the soil loss is most likely due to underestimated K- and R-factor values. Uncontrolled land use, deforestation, over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately lead to severe soil erosion Soil erosion is defined as “detachment” transportation and deposition of soil particles from one place to another under influence of wind or water. Variability in stand and soil structural properties were thought to contribute to the range in measured soil water loss at both a daily and seasonal scale.
