Estimating soil suction from electrical resistivity

Laboratory Electrical Resistivity Studies on Cement Stabilized Soil

Electrical resistivity measurement of freshly prepared uncured and cured soil-cement materials is done and the correlations between the factors controlling the performance of soil-cement and electrical resistivity are discussed in this paper. Conventional quality control of soil-cement quite often involves wastage of a lot of material, if it does not meet the strength criteria. In this study, i...

Soil moisture variability in a temperate deciduous forest: insights from electrical resistivity and throughfall data

In deciduous forests, soil moisture is an important driver of numerous physical, microbial, and biogeochemical processes. Therefore, characterizing the interactions between vegetation and soil moisture is critical to forecast long-term water resources and ecosystem health. However, these interactions are difficult to measure, both in time and space. Recent studies have shown the ability of elec...

DIVISION S-1—SOIL PHYSICS Electrical Resistivity Imaging for Detecting Soil Cracking at the Centimetric Scale

soil water content. Mackie-Dawson et al. (1989) studied the evolution of the cracking system in the first 10 cm Electrical resistivity measurements at high resolution (1.5-cm elecof soil by using vertical image analysis. They observed trode spacing) were performed to detect, from the soil surface, small cracks developing within the soil. We recorded a vertical electrical significant soil struct...

Electrical resistivity structure at the SAFOD site from magnetotelluric exploration

[1] The magnetotelluric dataset collected on the San Andreas Fault at Parkfield has been re-analyzed using superior inversion algorithms that have been developed in recent years. A combination of constrained inversion, forward modeling and synthetic inversion studies are used, and show that at the SAFOD site, the low resistivity fault zone extends to a depth of 2–3 km. An extended zone of low r...
