Journal ArticleDOI
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.
Journal ArticleDOI
Electrical resistivity tomography technique for landslide investigation: A review
TL;DR: A review of the main results obtained by applying 2D and 3D Electrical Resistivity Tomography (ERT) for the investigation of a wide spectrum of landslide phenomena which affected various geological formations and occurred in different geographic areas is presented in this paper.
Journal ArticleDOI
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.

Non-invasive moisture monitoring within an earth embankment — a precursor to failure
Peter Jackson,Kevin J. Northmore,Philip Meldrum,David Gunn,J. R. Hallam,J Wambura,B Wangusi,G Ogutu +7 more
TL;DR: In this article, an experimental monitoring system is described using electrical resistivity as a proxy for imaging changing moisture content distribution in engineered earthworks, illustrated using a case history concerning a road embankment constructed of tropical red soil in western Kenya.
Journal ArticleDOI
Geoelectric experimental design — Efficient acquisition and exploitation of complete pole-bipole data sets
TL;DR: This work presents a new, fully parallelized pole-bipole measuring strategy by which large amounts of data can be acquired swiftly and introduces a new experimental design concept that is based on “complete” data sets in terms of linear independence.

Geophysical investigation of the Sandalp rock avalanche deposits.
Laura Socco,Denis Jongmans,Daniele Boiero,Stefano Stocco,Margherita Maraschini,Ken Tokeshi,Didier Hantz +6 more
TL;DR: In this paper, the authors assess the potential of integrated geophysical methods to recognize and characterise a deposit created by two rock avalanches which occurred in the Sandalp valley (Switzerland) in 1996.

Application of Geophysical Methods to the Safety Analysis of an Earth Dam
TL;DR: In this article, a series of events occurred at an earth-filled dam which raised a serious question about the safety of the dam, and an integrated geophysical survey, including dc resistivity, controlled source magnetotelluric (CSMT), ground penetrating radar (GPR), and seismic refraction and tomography methods, has been conducted on the dam.
