Design of an automated tension infiltrometer for unsaturated hydraulic conductivity measurement [PDF]
A tension infiltrometer for field use, where both water level changes measurement and tension settings could be automated, was built in-house. Differential pressure transducers were used to automate the water level measurement in the reservoir.

Estimation of hydraulic conductivity function in unsaturated pyroclastic soils [PDF]
A full understanding of slope failure conditions in unsaturated pyroclastic slope needs a fair analysis of groundwater flow and, therefore, a proper hydraulic soil characterization in terms of either soil water retention curves (SWRC) and hydraulic ...

The Recovery of Soils after Compaction: A laboratory investigation into the effect of wet/dry cycles on bulk density and soil hydraulic functions [PDF]
Van den Akker et al. (2003) stated that “European subsoils are more threatened than ever in history” in an editorial referring to the results of the European Union concerted action “Experiences with the impact of subsoil compaction on soil crop growth ...

Previously Unrecognized Land-Use Control on Deep Soil CO<sub>2</sub> Sink. [PDF]
Transport‐limited, boundary‐conditioned bidirectional exchange of topsoil‐respired CO2 drives CO2 accumulation in less bioactive subsoils in concentrations that cannot be explained by in situ production alone and far exceed atmospheric boundary concentrations, revealing a production‐transport imbalance and a potential land‐use‐sensitive pathway for ...

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.

Experimental Study on Determining Unsaturated Property of Soil [PDF]
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

Experimental study on diffusion of chloride ions in unsaturated soils
Advection and diffusion are the mechanisms involved in contaminant transport in soils. The diffusion will be the dominant process when seepage velocity is low.

Prediction of unsaturated soil hydraulic conductivity with electrical conductivity [PDF]
Soil hydraulic conductivity (K) varies greatly with matric potential (h) and exhibits a high variability at the field scale. However, this key property for estimating water flux in soils is difficult to measure. In contrast, soil electrical conductivity (σ) is easier to measure and is influenced by the same parameters affecting K.

Analysis of unsaturated-saturated flow induced by a vadose zone well injection
Objective Vadose zone well (VZW) injection is an effective method of managed aquifer recharge (MAR). To improve VZW injection management, it is of great importance to accurately describe the unsaturated zone properties.
