On the spatio-temporal dynamics of soil moisture at the field scale
Harry Vereecken,Johan Alexander Huisman,Yakov Pachepsky,Carsten Montzka,J. van der Kruk,Heye Bogena,Lutz Weihermüller,Michael Herbst,Gonzalo Martinez,Jan Vanderborght +9 more
TL;DR: In this paper, the authors review the state of the art of characterizing and analyzing spatio-temporal dynamics of soil moisture content at the field scale and discuss measurement techniques that have become available in recent years and that provide unique opportunities to characterize field scale soil moisture variability with high spatial and temporal resolution.

Geophysical Monitoring of Moisture-Induced Landslides: A Review
J. Whiteley,J. Whiteley,Jonathan Chambers,Sebastian Uhlemann,Paul Wilkinson,J-Michael Kendall +5 more
TL;DR: Whiteley et al. as discussed by the authors presented a review of the state of the art of geophysical monitoring applied to moisture-induced landslides, focusing on technical and practical uses of time-lapse methods in geophysics applied to monitoring moistureinduced landslide.
Journal ArticleDOI
Life and death of slow-moving landslides
TL;DR: In the most destructive and catastrophic landslide events, rocks, soil and fluids can travel at speeds approaching several tens of metres per second as discussed by the authors, but slow-moving landslides rarely claim lives, they can cause major damage to infrastructure and sometimes fail catastrophically, transitioning into fast moving landslides that can result in thousands of casualties.

The simulation of finite ERT electrodes using the complete electrode model
Carsten Rücker,Thomas Günther +1 more
TL;DR: In this article, the authors present an approach for numerical computation applying the complete electrode model (CEM), which is known from medical imaging, and verify the modeling of electrical potential using an analytical solution for a perfectly coupled half-ellipsoid current source.

Detection of soil moisture and vegetation water abstraction in a Mediterranean natural area using electrical resistivity tomography
TL;DR: In this paper, electrical resistivity tomography (ERT) was used to measure soil moisture availability and plant water use in a Mediterranean natural area, and the authors found that ERT is a useful tool for measuring soil conditions, providing information on the spatial patterns within the soil and reaching depths otherwise inaccessible.

Application of geophysical measurements for assessing the role of fissures in water infiltration within a clay landslide (Trièves area, French Alps)
TL;DR: In this article, the authors investigated the role of fissures network in water infiltration in the numerous clay landslides of the Trieves area (French Alps) and found that the system of imbricated fissure drains water from the surface down to the shallow slip surfaces at 5 and 10-15 m.
Journal ArticleDOI
Estimation of clay content in soil based on resistivity modelling and laboratory measurements
TL;DR: In this paper, the authors developed a technique for estimating clay content that consists of the minimization of the difference between the theoretically calculated and measured soil resistivities as a function of water salinity.
