Soil erodibility factor is a criterion of soil particle resistance to detachment, transport, and effects of erosivity factors (rain drop, runoff, and wind) during the soil loss processes. In this study, non-linear support vector machines (SVMs) method was used for investigating the effects of some topography, soil physical and mechanical properties on soil erodibility in a part of Northern Karo...
Forests in Europe are currently not endangered by soil erosion. However, this can change with climate or intensified forest management practices. Using a newly established network of plots beech forests across Europe, the aims study were to (i) distinguish properties and erodibility indices relation bedrock, (ii) determine geochemical organic carbon (C org ) influencing erodibility, (iii) asses...
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...
Rill erosion is the detachment and transport of soil particles by concentrated flow of runoff. It is the most common form of water erosion in the hill slopes. Rill erodibility is the rate at which soil particle is detached and transported by shear force of the concentrated flow. The study was conducted to determine the rill erodibility in different soil textures in Zanjan province using a rainf...
* Corresponding author. USDA – ARS, SEWRL E-mail addresses: [email protected] (J. Cho), sm 1537-5110/$ – see front matter Published by doi:10.1016/j.biosystemseng.2009.01.007 Accurate simulation of cell-based processes is important for evaluating the impacts of best management practices (BMPs) on surface and ground water. The objective of this study was to evaluate the cell-based component of the Dyn...
[1] Whereas the existence of pronounced orbitally controlled periodicities is a major feature of Earth climate, its impact on landscape dynamics remains poorly understood. We use a Landscape Evolution Model (LEM) to systematically investigate the response of landscapes to a range of periodic oscillations in precipitation. The resulting sediment-flux evolution displays a pronounced sensitivity t...
Internal erosion is the second major reason for earth dam's failure after overtopping. One of the effective factors in internal erosion in earth dams is the clay minerals used in dams as well as the effects of compaction efforts on soil in sample preparation. In this research, internal erosion and the effect of clay minerals and compaction effort on internal erosion were investigated. For this ...
