Studies on soil erosion control

Effect of Nanoclay on Soil Erosion Control

Wind erosion is a widespread phenomenon in arid region. The purpose of this study was assessed the capacity of nanoclay to control soil erosion in wind tunnel experiment. The nanoclay isolated from soils was dominant in montmorillonite. A sandy soil from the Khara desert, nearly 100 km East of Isfahan (Central Iran) was used. The soils of this area are structurally unstable and sandy texture ma...

Application 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 ...

Soil Erosion: Its Prevention and Control

On the modelling of internal soil erosion

Suffusion is the process whereby fine particles are moved locally an transported through a coarse layer. This is a bulk erosion, which corresponds to a source term in the mass balance equations. This bulk erosion is counter intuitive, as erosion is basicaly an interfacial process. We suggest a framework within suffusion in a clayey sand can be viewed as a clay/water interface erosion at the mic...
