Notes on Avalanching and Dunes | Wind Erosion
Article shared by :
This article provides a note on avalanching and dunes. Avalanching: On an unprotected large eroding field, the rate of flow increases with distance to leeward side. Soil flow is zero at the windward edge of an eroding field, but the rate increases leeward until the flow becomes maximum for the wind of specific velocity. This […]
Understanding the Mechanics of Soil Movement by Wind
Article shared by :
Wind erosion is mainly a surface phenomenon and is influenced directly by wind velocity in various strata near the ground through which soil particles rise in saltation. Therefore, a brief discussion about wind structure near the ground would be necessary for understanding the mechanics of soil movement by wind. Wind Structure Near the Ground: The […]
