Wind-borne sand mass flux in vegetated surfaces – Wind tunnel experiments with live plants

摘要: Abstract To develop our knowledge of the impact different vegetation types on aeolian sand flux, a series experiments conducted in wind tunnel monitored mass flux over bare surface and relation to planted two live plants, Cosmos bipinnatus Ligustrum lucidum Ait, at plant densities. Normalized sediment decreased with increasing height surface. However, plants affected transport system by modifying vertical distribution within above vegetated Sand reduced from low high density below but this pattern reversed Observations horizontal profiles indicated was transported areas both all In density, trend similar medium increased slightly beyond for types. upwind edge middle barrier, downwind end densities revealed influence drag versus turbulence produced plants. At certain distance area, flux. Although varying between types, overall unplanted configurations.
