Drought is one of the worst natural disasters that affect the economic, social, and
environmental status of any country. The long-term drought affects the soil ecosystem and …

The concept of tortuosity is used to characterize the structure of porous media, to estimate
their electrical and hydraulic conductivity, and to study the travel time and length for tracer …

The aim of this study was to investigate the effects of biochar amendment on soil aggregate
formation and stability, and soil hydraulic properties. Biochar produced from dairy manure …

In heterogeneous structured soils, water and transported dissolved substances and
suspended particles and colloids may under certain conditions bypass most of the soil …

Core Ideas Movement of O2 in the soil is mainly diffusive. Respiration consists of plant root
and microbial O2 uptake, roughly of the same magnitude. Reduced O2 and elevated CO2 …

Crop rotations that include tap-rooted species of cover crops may help alleviate the
deleterious effects of soil compaction on plant growth by modifying soil physical properties …

Prediction of relative permeability in unsaturated porous media is important for oil and gas
reservoir engineering and hydrology as well as chemical engineering. A physical …

Soil surface is the locus of complex apportioning of mass and energy reaching the Earth.
Pore system functioning of the surface soil, particularly airflow within the soil matrix, is …

Soil compaction by vehicular traffic modifies the pore structure and soil hydraulic properties.
These changes potentially influence the occurrence of preferential flow, which so far has …

Dynamics of flowing air in partially water‐saturated, porous geological formations are
governed by a wide range of forces and parameters. These dynamics are reviewed in the …
