spatial variability of soil erodibility factor (k) of the usle in north west of iran
the soil erodibility factor varies spatially according to variations of some soil properties on the surface. this study was carried out to compare spatial variability of the soil erodibility factor as estimated and measured using the usle. the study was conducted in an agricultural zone with an area of in 900 km2 in hashtrood, northwestern iran. in the study area, 36 square grids with a dimensi...
متن کاملMeasure Soil Erodibility in Situ
The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...
متن کاملAnalyzing the Changes of Soil Erodibility Index (K) in the Soils of Arid Regions and the Effective Factors in Central Iran (Case Study: Yazd-Ardakan Plain)
One of the main factors of water erosion is the natural characteristics of the soil called "erodibility" or"detachability". The present study aims to analyze the variations of soil erodibility factor in different plains and thefactors related to it. Erodibility is one the key factors in some models of erosion and sediment such as Universal SoilLoss Equation (USLE), Revised USLE (RUSLE), and Mod...
متن کاملevaluation of soil erodibility factor (k) forloess derived landforms of kechik watershedin golestan province
introduction: globally, soil erosion is a principal degradation process resulting in negative impacts on different soil functions (food and other biomass production, water storing, filtering and transformation, habitat and gene pool, physical and cultural environment for mankind, and source of raw materials) which ultimately causes irreversible effect on the poorly renewable soil resource. dete...
متن کاملuncertainty of the soil erodibility factor (k), estimated using the usle nomograph in calcareous soils of hashtrood, (north-west of iran)
in the universal soil loss equation (usle), soil erodibility factor (k) is estimated through nomograph. using the nomograph in calcareous soils may lead to uncertainty in estimating the erodibility factor. this study was conducted in hashtrud, (north west of iran) from march 2005 to march 2006. field measurements were carried out in an agricultural area of 30 km × 30 km. thirty six land grids w...
