CHANGE OF SPLASH EROSION RATE IN RAINFALL DIFFERENT DURATION AND INTENSITY ON MARL SOILS
Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersion of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research, the effect of various rainfall intensity (60, 90 and 120 mm/hr) on the ...
متن کاملApplication of Polyacrylamide for Splash Erosion Control on Marl Soil
Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersement of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research,the effect of various polyacrylamide (PAM)values (0, 0.2, 0.4 and 0.6 ...
متن کاملTemporal Variation of Interrill Erosion Affected by Slope Gradient in Soils with Different Texture
The process of splash of soil particles by raindrops and their transport by splash or surface shallow flow is considered as interrill erosion, which can reduce soil fertility and cause pollution of surface water. This research was carried out to investigate the temporal variation of interrill erosion in different soils affected by surface slope. For this purpose, laboratory experiments were car...
متن کاملمطالعه آزمایشگاهی فرسایش پاشمانی و ارتباط آن با برخی خصوصیات خاک در سه کاربری اراضی مجاور هم (مطالعه موردی: حوزه آبخیز کسیلیان)
As the first event in soil erosion, rain splash erosion causes movement of soil fragments. Splash is an important process in interrill erosion. The amount of soil particles detached from the surface is associated with soil and rain characteristics and may be affected by rainfall erosivity and soil erodibility. Therefore, in this study, splash erosion rate and its relation with some soil propert...
متن کاملChanges study of soil splash and stability of soil aggregates using polyvinyl acetate
Soil erosion, especially water erosion, threatens the installations, water resources and also human life. The first stage of water erosion is the splash erosion that it requires to control in the primary stages. On the other hand, the application of soil conditioners is one of the approaches that it provide the conservation possibility of soil surface against water erosion, especially erosion f...
