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.

4-D inversion of DC resistivity monitoring data acquired over a dynamically changing earth model
TL;DR: In this paper, a least squares inversion algorithm is proposed to allow for the subsurface properties to continuously change in time, and the regularizations not only in the space domain but also in time are introduced to reduce inversion artifacts and improve stability of the inverse problem.

Improved strategies for the automatic selection of optimized sets of electrical resistivity tomography measurement configurations
TL;DR: In this paper, two strategies for obtaining the maximum spatial resolution in electrical resistivity were presented for tomography surveys using a limited number of four-electrode measurement configurations, and their execution times were analyzed in terms of the number of cells in the inverse model.

DC-resistivity mapping of internal landfill structures: two pre-excavation surveys
TL;DR: In this paper, a 2-D DC resistivity analysis was carried out on old parts of two similar landfills, with waste of different ages, to test the capability of the resistivity method as a pre-characterization technique.
