Total and Matric Suction in Unsaturated Soil with the Existence of Different Salts Content [PDF]
Engineering and Technology Journal, 2013 Soils located above the groundwater table are generally unsaturated and exhibit negative pore-water pressures. A soil-water characteristic curve (SWCC) that relates the water content of a soil to matric suction is an important relationship for the ...

Experimental Study on Determining Unsaturated Property of Soil [PDF]
, 1980 This paper deals with the experimental study of hydraulic properties of unsaturated soil. In treating unsaturated zone, a great deal more data are required than are required for the saturated zone, but these properties of soils must be known to apply the

An elasto-plastic model of unsaturated soil with an explicit degree of saturation-dependent CSL
Engineering Geology, 2019 Use of a sophisticated model to conduct simulation analysis of both contractive and dilative behaviours in unsaturated soils during the shear stage remains challenging. This paper presents an elasto-plastic model having two plastic deformation mechanisms—

Carbon Energy, EarlyView.Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Influence of biochar addition on gas permeability in unsaturated soil
Geotechnique Letters, 2019 Biochar (BC) has been proposed as an alternative soil amendment in landfill cover. Its effects on soil hydraulic properties (e.g.
