Effects of coarse-fragment content and size on soil erosion under simulated rainfall

Impact of Rainfall Microstructure on Erosivity and Splash Soil Erosion Under Simulated Rainfall

soil 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...

The effect of surface rock fragments deployment pattern on soil erosion processes under simulated conditions

Extended abstract 1- Introduction The Soil surface characteristics have significant effects on the erosion process. The wide areas of watershed soil surfaces are covered with considerable amounts of rocks and pebbles. Surface rock fragments, resulting in water connectivity, change during the erosion process. Rock fragments on the soil surface may increase the infiltration and reduce soil loss...

Hysteretic sediment fluxes in rainfall-driven soil erosion: Particle size effects

A detailed laboratory study was conducted to examine the effects of particle size on hysteretic sediment transport under time-varying rainfall. A rainfall pattern composed of seven sequential stepwise varying rainfall intensities (30, 37.5, 45, 60, 45, 37.5, and 30 mm h), each of 20 min duration, was applied to a 5 m 3 2 m soil erosion flume. The soil in the flume was initially dried, ploughed ...
