Characterising the impact of rainfall on dustfall rates

open access: yesClean Air Journal, 2016
Soil moisture increased the cohesion potential between particles, reducing the ability of the particle to be entrained. Dust suppression techniques are designed to increase soil moisture and therefore soil cohesion through the application of water or ...
