Sediment delivery of partially-unfrozen loam soil rill by snow/glacier meltwater flow

An experimental study of rill sediment delivery in purple soil, using the volume-replacement method

Experimental studies provide a basis for understanding the mechanisms of rill erosion and can provide estimates for parameter values in physical models simulating the erosion process. In this study, we investigated sediment delivery during rill erosion in purple soil. We used the volume-replacement method to measure the volume of eroded soil and hence estimate the mass of eroded soil. A 12 m ar...

Selectivity of Particles through Rill Erosion in Different Soil Textures

Sediment selectivity during transport may provide basic information for evaluating on-site and off-site impacts of the soil erosion. Limited information is, however, available on the selectivity of sediments in rill erosion, particularly in the rainfed furrows. Toward this, the sediment selectivity was investigated in three soil textures (loam, loamy sand sand clay loam) under 10% slope using 9...

Cob Removal Effect on Sediment and Runoff Nutrient Loss from a Silt Loam Soil

تعیین فرسایش‌پذیری شیاری در برخی خاک‌های استان زنجان تحت باران شبیه‌سازی ‌شده

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...

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...
