Prediction of unsaturated permeability curve of compaction loess with pore-size distribution curve and its application scope

open access: yesRock and Soil Mechanics, 2021
The unsaturated permeability curve is governed by the pore-size distribution curve, which can be used to predict the permeability curve. In order to investigate the applicability of this method for compacted loess, three groups of compacted loess samples

Soil–aquifer phenomena affecting groundwater under vertisols: a review [PDF]

open access: yesHydrology and Earth System Sciences, 2016
Vertisols are cracking clayey soils that (i) usually form in alluvial lowlands where, normally, groundwater pools into aquifers; (ii) have different types of voids (due to cracking), which make flow and transport of water, solutes and gas complex; and ...
