A Review of the Effects of Surface Moisture Content on Aeolian Sand Transport

摘要: Over the past several decades, a number of studies have shown that intergranular cohesion associated with presence moisture significantly increases critical shear velocity required to initiate motion in sand grains, and decreases transport rates. This paper examines currently available models effects compares model predictions for hypothetical situations. Model exhibit considerable disagreement regarding magnitude effects. For 0.27-mm sands, predicted threshold 1% content ranged from about 8% 148% expected dry velocity, 4% increased 47%–206% value. Based on velocities, rates at under 0.50 m s−1 range no more than 100 kg m−1 hr−1.
