Determining soil erosion and threshold friction velocity at different soil moisture conditions using a portable wind tunnel KU Leuven
Measurements with a portable wind tunnel were performed to study the effect of surface soil moisture (upper 3 cm of the soil) on threshold friction velocity, horizontal sediment flux and airborne dust concentration above wind-eroding soils. Eleven soils near the city of Ahwaz, Iran were tested. Soils were generally silty and saline-calcareous, with low organic matter. As soil moisture increased threshold friction velocities increased, but ...
