Temporal Variation Pattern of Runoff Generation and Rill Erosion in Different Soils and Slope Gradients
This study was conducted to investigate the temporal variations of runoff and rill erosion in various soil textures under different slope gradients. So, a laboratory experiment was set up in three soil textures (loam, clay loam, and sandy clay loam) and four slope gradients (5, 10, 15, and 20%) using the completely randomized design with three replications. Runoff production and rill erosion we...
متن کاملInvestigating Land Use and Slope Effects on Soil Properties, Runoff and Sediment Using Rainfall Simulator Case Study of Kechik Watershed in Golestan Province
INTRODUCTION Soil erosion and its issues are among the most important environmental challenges. In many areas, soil erosion affected valuable natural resources and soil fertility. The recognition of the factors affecting runoff and soil erosion, and the determination of their issues are essential for soil and water management conducive to sustainable development. The assessment and analysi...
متن کاملsoil erosion under simulated rainfall in loess lands with emphasis on land-use, slope and aspect
the runoff generation and soil erosion in the kechik watershed, golestan province, was assessed, using a designed and constructed portable rainfall simulator. treatments were applied on different land-uses, slopes and aspects as the most influential factors. results showed that land-use significantly affected runoff generation (13.35 l, 6.9 l, and 4.12 l, respectively for agriculture, forest an...
متن کاملDetermination of Susceptibility to Rill and Interrill Erosion of some Semi-Arid Soils using Rainfall Simulator in Laboratory Conditions
In semi-arid regions, soils are weakly aggregated and subjected to water erosion processes especially rill and interrill erosion. There is no information on the rate of these water erosion types in semi-arid soils located in the hillslopes. Therefore, this study was conducted to determine the soils susceptibility to these erosion types in semi-arid region. A laboratory experiment was done in ei...
متن کاملExperimental Investigation of Rill Creating Hydraulic Conditions in the Marl Rangelands in a Tilting Flume
Generally, the evaluation and assessment of the critical condition of rill formation are useful for a better understanding of soil erosion processes. The inherence characteristics of soils, which have much dynamic variations on the hillslopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. This study aims to assess experimental rill incision ...
