This paper aims to provide a state-of-the-art review on the effects of vegetation roots on the
soil structure and soil hydraulic properties. After a thorough review of current studies, the …

Use of biochar as a soil amendment for climate change mitigation and environmental
remediation has been intensively studied over the past decade, yet the growing interest in …

Because direct measurement is time-consuming and costly, the permeability function of
unsaturated soil is commonly determined by estimation using the soil–water characteristic …

An unsaturated soil is a three-phase material that is ubiquitous on the earth's surface. The
fully saturated and completely dry states are just two limiting conditions of an unsaturated …

This work reviews the transient two-phase flow in porous media with engineering
applications in Geotechnics. It initially overviews constitutive relationships, conventional …

The ink-bottle effect, resulting from the non-uniformity of pore structure, plays a significant
role in the hydraulic behaviour of soils. In this paper, a series of laboratory tests including …

This state-of-the-art covers advances in the constitutive modelling, experimental
investigation and field measurement of suction for unsaturated soils. It consists of three …

Water retention in compacted clays is dominated by multi‐modal pore size distribution which
evolves during hydro‐mechanical paths depending on water content and stress history. A …

Air permeability of soils reflects the ability to allow the passage of air, which is significantly
important to explore related issues in geotechnical, environmental, agricultural, and …

Effects of plant roots on changes of soil hydraulic properties, including soil water retention
curves (SWRC) and soil hydraulic conductivity functions (SHCF), are not well understood …
