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.

Using the resistivity method for leakage detection in a blind test at the Røssvatn embankment dam test facility in Norway
TL;DR: In this article, a test was conducted on a rockfill embankment dam with a central glacial till core at the Rossvatn test facility in Norway, where three defects, consisting of permeable material, were built into the dam at various depths and locations unknown to the personnel carrying out the measurements and data interpretation.

Optimization of ERT Surveys for Monitoring Transient Hydrological Events Using Perturbation Sensitivity and Genetic Algorithms
TL;DR: In this article, a simple yet powerful algorithm is presented for the optimal allocation of electrical resistivity tomography (ERT) electrodes to maximize measurement quality, making use of a definition of the sensitivity of an ERT array to a series of subsurface perturbations.
