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

Although it has many positive effects, soil structure may adversely affect the filtering function
of the vadose zone that protects natural water resources from various sources of pollution …

The one-dimensional convection–dispersion equation is often used to estimate the risk of
nonpoint source groundwater contamination and the dispersivity in this equation is known to …

In this paper we briefly review some aspects of the soil water balance, highlighting the
possible connections and feedbacks among the various processes as well as pointing out …

Computed tomography (CT) provides a nondestructive means of observing soil structure
and monitoring solute breakthrough in real time. We investigated an intact soil column 10 cm …

Soil moisture conditions are an important interface between agriculture and the
environment, as they impact on the length of the grazing season, grass growth rate and …

We introduce an improved, one-dimensional, non-steady-state dual-permeability model
(MACRO 5.1). The model simulates water flow and solute transport in the vadose zone of …

A key problem facing soil physics and hydropedology at present is some of the standard
theories of water flow in soils do not fully reflect the processes at the pore scale, and thus …

Adding carbon-rich solids from pyrolysis (pyrochars) and hydrothermal carbonization
(hydrochars) to soils can improve their hydraulic properties and increase the plant available …

We present a method to quantify preferential flow in the unsaturated zone of cropped soils.
This method was developed for bare soils (Stumpp et al., 2007) and is now applied to a …
