introduction soil losses and erosion is one of the main causes of fertility decreasing, sedimentation in river cannels and irrigation canals, decreasing of storage capacity in dams, increasing of floods frequency, environmental pollution and it prevents from stable development. more than 70% of iran land is covered with arid and semi-arid areas. soil erosion as one of the main causes of soil de...

The USLE and the RUSLE are two common erosion prediction models that used worldwide, soil erodibility (K-factor) is one parameter to calculate them. objectives of this study were investigate variability soil-erodibility factors under different soil-texture classes evaluate efficiency diffuse reflectance spectroscopy (DRS) in near-infrared range at predicting K-factors using a partial least squa...

Mineral dust in the atmosphere has implications for Earth’s radiation budget, biogeochemical cycles, hydrological cycles, human health, and visibility. Currently, the simulated vertical mass flux of dust differs greatly among the existing dust models. While most of the models utilize an erodibility factor to characterize dust sources, this factor is assumed to be static, without sufficient char...

Data from the Catsop catchment in South Limburg, Netherlands was simulated with the model KINEROS2. The results of calibration and validation on a split set of runoff and sediment data are reported and the variations in apparent parameters are analyzed. Calibration was performed with regard to the temporal distribution of runoff and sediment rather than single values such as total or peak rates...

A flume study was conducted using a soil, yard waste compost, and an erosion control compost to investigate the response to concentrated flow and determine if the shear stress model could be used to describe the response. Yard waste compost (YWC) and the bare Cecil soil (CS) control responded to concentrated laboratory runoff similarly in rill formation, and the shear stress model was useful in...

The soils of Gadas, object the present study, are identified on macromorphological, physico-chemical level and indices erodibility related to their properties. analyzes were carried out by standard methods. macromorphological analysis a toposequence made it possible identify five types soils: lithosols which occupy high zones landscape, colluvial (arenosols, regosols) located piedmont, alluvial...
