Published in 2019 at "KSCE Journal of Civil Engineering"

DOI: 10.1007/s12205-019-1344-z

Abstract: Several studies aimed at linking hydraulic conductivity at saturation (Kw,s) to air permeability (Ka(θw)) of soil at given water content (θw) since it can be measured more rapidly and nondestructively than Kw,s especially regarding some… read more here.
